    My SAT Prep Journey: The Question I Got Wrong in Mock Test 4

    |

    SAT preparation has been really tough for me with lots of ups and downs and lots of learning. Let’s talk about my SAT prep experience: what I did, where I struggled and how I overcame all the obstacles that came in my way. Believe me If I could do it, then you can also do it. So, let’s start.

    First of all, I was too keen on getting a good score in the SAT exam. So, I began preparing for that. I prepared hard at my own level and I was too happy at that time and felt that I am well prepared to appear for the SAT exam. Therefore, I considered taking the SAT Mock Test provided on the official website because I was quite sure that mock tests would be the deciding factor in determining where I was standing. So, I start with Math on the SAT Mock Test 4 and guess what? This test taught me a lesson which I hadn‘t anticipated

    My Mock Test 4 Experience

    When I began, I realized that the questions were relatively simple and easy to manage initially but when I progressed further, the questions were becoming difficult for me to solve and at that time, I began losing my confidence. Nonetheless, I finished both modules as this would assist me in identifying my weak points where I could work upon.

    Now this is the time when I went through my answers and the outcome was really shocking for me. I was able to get 530 in Module1 and 530 in Module2. Since I was anticipating a better score, I began going through the answers to know where I went wrong.

    The Question I Got Wrong

    Lets talk about the questions that I answered incorrectly from both modules and the challenges that I encountered in solving them.

    From Module 1:

    1. Hana deposited a fixed amount into her bank account each month. The function \(f(t) = 100 + 25t\) gives the amount, in dollars, in Hana's bank account after \(t\) monthly deposits. What is the best interpretation of \(25\) in this context?
    A) With each monthly deposit, the amount in Hana's bank account increased by $\(25\).
    B) Before Hana made any monthly deposits, the amount in her bank account was $\(25\).
    C) After \(1\) monthly deposit, the amount in Hana's bank account was $\(25\).
    D) Hana made a total of \(25\) monthly deposits.
    Explanation

    Now, this question comes from the category: Linear functions. My Answer: D) but the correct answer is A). While reading this question, I didn’t give much time to understand the question and due to my negligence, I ended up selecting the wrong answer.

    Sat Figure1
    2. Right triangles \(PQR\) and \(STU\) are similar, where \(P\) corresponds to \(S\). If the measure of angle \(Q\) is \(18^\circ\), what is the measure of angle \(S\) ?
    A) \(18^\circ\)
    B) \(72^\circ\).
    C) \(82^\circ\).
    D) \(162^\circ\)
    Explanation

    Now, this question comes from the category: Lines, angles, and triangles. My Answer: A) but the correct answer is B). While solving this question, I realized that my concepts on this topic were not strong enough which made me give the wrong answer.

    3. The scatterplot shows the relationship between two variables, \(x\) and \(y\)
    Sat Figure 2
    Which of the following equations is the most appropriate linear model for the data shown ?
    A) \(y=0.9+9.4x\)
    B) \(y=0.9-9.4x\).
    C) \(y=9.4+0.9x\).
    D) \(y=9.4-0.9x\)
    Explanation

    Now, this question comes from the category: Two-variable data. My Answer: A) but the correct answer is D). While solving this question, I realized that my concepts on this topic were not strong enough which made me give the wrong answer.

    Sat Figure 3
    4. What is an equation of the graph shown ?
    A) \(y=-2x-8\)
    B) \(y=x-8\).
    C) \(y=-x-8\).
    D) \(y=2x-8\)
    Explanation

    Now, this question comes from the category: Linear equations in two variables. My Answer: A) but the correct answer is C). Honestly, this question was not that hard but I didn’t pay much attention to the details and regretted it later as my concepts were clear for this question.

    5. \(\frac{\Large 14x}{\Large 7y}= 2\sqrt{w+19}\)
    The given equation relates the distinct positive real numbers \(w\), \(x\), and \(y\). Which equation correctly expresses \(w\) in terms of \(x\) and \(y\) ?
    A) \(w=\sqrt{\frac{\Large x}{\Large y}}-19\).

    B) \(w=\sqrt{\frac{ \Large 28x}{\Large 14y}}-19\).

    C) \(w = \left(\frac{\Large x}{\Large y}\right)^2 - 19\).

    D) \(w = \left(\frac{\Large 28x}{\Large 14y}\right)^2 - 19\).
    Explanation

    Now, this question comes from the category: Equivalent expressions. My Answer: A) but the correct answer is C). Honestly, this question was not that hard but I realized that I made a calculation mistake at the last step which made my whole answer incorrect.

    6. Point \(O\) is the center of a circle. The measure of arc \(RS\) on this circle is \(100^\circ\). What is the measure, in degrees, of its associated angle \(ROS\) ?
    Explanation

    This question comes from the category: Circles. I didn’t attempt this question as I was completely clueless about the method of solving this question.

    7. [The expression \(6^5\sqrt{ 3^5 x^{45}}. \sqrt[8]{2^8x}\) is equivalent to \(ax^b\) , where \(a\) and \(b\) are positive constants and \(x > 1\). What is the value of \(a + b\) ?
    Explanation

    Now, this question comes from the category: Equivalent expressions. This question was also not difficult to attempt but I didn’t give much time to this question because of the limited time. So, I skipped that question too. 

    8. A right triangle has sides of length \(2\sqrt{2}\), \(6\sqrt{2}\), and \(\sqrt{80}\) units.What is the area of the triangle, in square units ?
    A) \(8\sqrt{2} + \sqrt{80}\).
    B) \(12\).
    C) \(24\sqrt{80}\).
    D) \(24\).
    Explanation

    Now, this question comes from the category: Right triangles and trigonometry. This question was also not difficult to attempt but I didn’t give much time to this question because of the limited time. So, I skipped that question too. 

    9. In the \(xy\)-plane, a parabola has vertex \((9, -14)\) and intersects the \(x\)-axis at two points. If the equation of the parabola is written in the form \(y = ax^2 + bx + c\), where \(a\), \(b\), and \(c\) are constants, which of the following could be the value of \(a\)+ \(b\) + \(c\) ?
    A) \(-23\).
    B) \(-19\).
    C) \(-14\).
    D) \(-12\).
    Explanation

    Now, this question comes from the category: Linear functions. My Answer: D) but the correct answer is A). While reading this question, I didn’t give much time to understand the question and due to my negligence, I ended up selecting the wrong answer.

    From Module 2:

    10. Which expression is equivalent to \(12x^3-5x^3\) ?
    A) \(7x^6\).
    B) \(17x^3\).
    C) \(7x^3\).
    D) \(17x^6\).
    Explanation

    Can you believe it?..Someone who is preparing for the SAT can give the wrong answer to this question? But, I did. Yes, I admit my mistake that due to my negligence and limited time, I panicked and ended up giving the wrong answer, even to this question. Unbelievable!!

    11. A proposal for a new library was included on an election ballot. A radio show stated that 3 times as many people voted in favor of the proposal as people who voted against it. A social media post reported that 15,000 more people voted in favor of the proposal than voted against it. Based on these data, how many people voted against the proposal?
    A) \(7,500\).
    B) \(15,000\).
    C) \(22,500\).
    D) \(45,000\).
    Explanation

    Now, this question comes from the category: Linear Equations in Two Variables. My Answer: D) but the correct answer is A). I found this question a little complicated to understand which made me give the wrong answer.

    12. \(f(x)=(x-10)(x+13)\)

    The function \(f\) is defined by the given equation. For what value of \(x\) does \(f(x)\) reach its minimum ?
    A) \(-130\).

    B) \(-13\).

    C) \(-\frac{\Large 23}{\Large 2}\).

    D) \(-\frac{\Large 3}{\Large 2}\).
    Explanation

    This question was based on Calculus and I was completely aware of the concept, even I applied it too. but I realized that I made a calculation mistake at the last step which made my whole answer incorrect. My Answer: A) but the correct answer is D). You know, it feels very bad when you know how to solve the question but end up making a calculation mistake. A regretful moment for me.

    13. The function \(f(x)=\frac{\Large 1}{\Large 9}(x-7)^2+3\) gives a metal Ball's height above the ground \(f(x)\), in inches, \(x\) seconds after it started moving on a track, where \(0\leq x\leq10\). Which of the following is the best interpretation of the vertex of the graph of \(y=f(x)\) in the \(xy\)-plane ?
    A) The metal ball's minimum height was \(3\) inches above the ground.
    B) The metal ball's minimum height was \(7\) inches above the ground.
    C) The metal ball's height was \(3\) inches above the ground when it started moving.
    D) The metal ball's height was \(7\) inches above the ground when it started moving.
    Explanation

    This question was also not difficult to attempt but I didn’t give much time to this question because of the limited time. So, I skipped that question. 

    14. If a new graph of three linear equations is created using the system of equations shown and the equation \(x + 4y = -16\), how many solutions \((x,y)\) will the resulting system of three equations have ?
    Sat Figure 4
    A) Zero
    B) Exactly One
    C) Exactly two
    D) Infinitely many
    Explanation

    To be honest, I was not completely sure about the answer of this question, so I made a quick guess and guess what? I guessed it wrong. My Answer: B) but the correct answer is A). 

    15. \(f(x)=5,470(0.64)^\frac{\Large x}{\Large 12}\)

    The function \(f\) gives the value, in dollars, of a certain piece of equipment after \(x\) months of use. If the value of the equipment decreases each \(\underline{year}\) by \(p\%\) of its value the preceding year, what is the value of \(p\) ?
    A) \(4\)
    B) \(5\)
    C) \(36\)
    D) \(64\)
    Explanation

    This question was taking me time to grasp the exact concept of this question and due to limited time. So, I skipped that question. 

    16. The equation \(x^2+(y-1)^2=49\) represents circle \(A\). Circle \(B\) is obtained by shifting circle \(A\) down \(2\) units in the \(xy\)-plane. Which of the following equations represents circle \(B\) ?
    A) \((x-2)^2+(y-1)^2=49\)
    B) \(x^2+(y-3)^2=49\).
    C) \((x+2)^2+(y-1)^2=49\)
    D) \(x^2+(y+1)^2=49\)
    Explanation

    Now while solving this question, I was pretty sure that my answer would be right as I have already practiced these types of questions earlier, but this was a time of reality check. My answer was incorrect, even I was disappointed. Probably, my concepts were still not strong at that time. 

    17. Two identical rectangular prisms each have a height of \(90\) centimeters \((cm)\). The base of each prism is a square, and the surface area of each prism is \(K cm^2\) . If the prisms are glued together along a square base, the resulting prism has a surface area of \(\frac{\Large 92}{\Large 47}K cm^2\) What is the side length, in \(cm\), of each square base ?
    A) \(4\)
    B) \(8\).
    C) \(9\)
    D) \(16\)
    Explanation

    This question was taking me time to grasp the exact concept of this question and due to limited time. So, I skipped that question. 

    What I Learned from My Mistakes

    Honestly, these mistakes discouraged me a little while reviewing the correct answers. But, it was a reminder that confidence can sometimes lead to carelessness. I realized that overconfidence can be just as dangerous as lack of knowledge. Every detail matters, and I needed to train myself to double-check, even when I was sure I was right. 

    The main lesson I learned? Slow down and read carefully, especially on questions that seem straightforward at first. 

    Measures Taken By Me To Improve My Practice and Overall Score

    After taking Mock Test 4, I made some changes in my preparation strategy. First, I started practicing similar problems on topics: Circles, Right triangles and trigonometry, Power and Indices and Algebraic Expressions, and Linear equations in two variables to have a strong grip of these concepts into my brain. As there were some questions which I might be able to crack but due to limited time, I skipped them. So, I also worked on Time Management. I began solving questions by setting the timer to ensure accuracy over speed. Now, my new motive is: slow is smooth, and smooth is fast.

    Additionally, I began reviewing every question I got right and wrong after giving each mock test which helps me realize where I am improving. Sometimes, the questions you get right by guessing or rushing are the ones you need to revisit the most. This approach helped me identify my small mistakes before they became big problems on test day.

    Additional Resources Which Helped Me in My SAT Prep Journey

    Beyond mock tests, there were some other resources as well which played a crucial role in my SAT preparation journey and helped me improve my score. Check out these extra resources:

    My Final Thoughts and Advice

    Mock Test 4 was a turning point in my SAT preparation journey. The questions I got wrong were not really the hardest ones, but they were the most important for me because of the lesson they carried. 

    If you are a student preparing for the SAT exam, then I suggest you practice more and more questions. You can even explore multiple platforms where the Mock tests are given. If you are not sure how and where to start, then I recommend you to take this SAT Math Prep Course by Moonpreneur. Always remember the mistakes you make in mock tests aren’t failures, in fact, they are the opportunities to make you better. 

    This was my SAT Prep Journey. Hope you find it helpful. Remember, If I can improve myself, then you too can. Last but not the least, the final piece of advice I want to give you is: embrace the mistakes because every wrong answer tells you what you need to fix. Don’t rush. Read carefully. And remember, it’s better to stumble now than on the real test.

    Mock tests are where you learn, the SAT is where you show what you’ve learned. So practice, be patient and trust the process and see the magic!! All the best for your SAT Preparation Journey!!!.
