💻 AP Computer Science A Medium
Consider the following static method.
  1. A. return 4 * n;
  2. B. return 8 * n;
  3. C. return 64 * n;
  4. D. return (int) Math.pow(n, 4);
  5. E. return (int) Math.pow(n, 8); ✓
Explanation: The algorithm recursively squares the result of itself, effectively doubling the exponent at each step. Starting with a base case that returns $n$, the first recursive call yields $n^2$, the next yields $(n^2)^2 = n^4$, and the final step produces $(n^4)^2 = n^8$. This pattern demonstrates that the method computes $n^8$, making option (E) correct. Option (D) is a common trap because it assumes the exponent matches the number of recursive calls or the depth of the stack, but the squaring operation compounds the power exponentially rather than linearly.

Which of the following angles has the same terminal side as ?
  1. A. –720°
  2. B. –300°
  3. C. –60°
  4. D. 60° ✓
  5. E. 720°
Explanation: Two angles are coterminal if they share the same terminal side, which occurs when their difference is an integer multiple of 360°. Since $60^\circ - (-720^\circ) = 780^\circ$ and $780 \div 360$ is not an integer, choice (A) is incorrect; however, checking the options against a standard reference angle like $60^\circ$, only choice (D) represents the angle itself. The question likely implies finding the coterminal angle within a specific range or simply identifying the given angle as its own coterminal representation among the choices, making 60° the correct selection as it is the primary angle defining that terminal side.
🧪 AP Chemistry Medium
How many milliliters of 0.100 M H _{2} SO _{4} are required to neutralize 50.0 mL of 0.200 M KOH?
  1. A. 25.0 mL
  2. B. 30.0 mL
  3. C. 20.0 mL
  4. D. 50.0 mL ✓
Explanation: D —The reaction is H _{2} SO _{4} (aq) + 2 KOH(aq) → K _{2} SO _{4} (aq) + 2 H _{2} O(l). The calculation is:
✍️ AP English Language Medium
In sentence 7 (reproduced below), which of the following versions of the underlined text best establishes the writer’s position on the main argument of the passage?
  1. A. (as it is now)
  2. B. With the privatization of space exploration still in its infancy,
  3. C. Unless a gentlemen’s agreement of understanding by like-minded countries is signed,
  4. D. Barring a pact by the world’s countries to monitor and impose strict rules of access to certain areas of space, ✓
  5. E. Russia, Japan, the U.S., and other countries must pledge to mend their careless ways or
Explanation: spells out what the writer believes needs to be done to prevent catastrophe in space. The other choices are either irrelevant or too vague to solve the problem.
🎓 GRE Prep Medium
Before last night’s game, a basketball player had scored an average (arithmetic mean) of 20 points per game. She scored 25 points in last night’s game, raising her average to 21 points per game. How many games did she play before last night’s game?
  1. A. 3
  2. B. 4 ✓
  3. C. 5
  4. D. 6
Explanation: Let $n$ be the number of games before last night. Total points before = $20n$. After scoring 25 in the $(n+1)$th game, new average = $\frac{20n + 25}{n+1} = 21$. Solving: $20n + 25 = 21(n+1) \Rightarrow 20n + 25 = 21n + 21 \Rightarrow 4 = n$. So she played 4 games before.
📖 SAT Reading & Writing Hard
The student wants to correct a likely misconception about flying squirrels. Which choice most effectively uses relevant information from the notes to accomplish this goal?
  1. A. Flying squirrels can usually be observed at night as opposed to the day.
  2. B. Despite their name, flying squirrels glide rather than fly. ✓
  3. C. While hunting poses a threat to flying squirrels, habitat loss is ultimately the greater danger.
  4. D. Even though flying squirrels are scarce in Ohio, they can still be easily seen.
Explanation: The correct answer is (B) because it directly addresses the most common misconception regarding the animal's name by clarifying that they glide on patagium membranes rather than actively fly like birds or insects. This choice effectively uses relevant information to correct the student's likely misunderstanding of their locomotion method. Options (A), (C), and (D) discuss activity patterns, threats, or population density, which do not address the specific misconception about how they move through the air.

💡 Study Tips

🎯 Know the test format before test day

Familiarize yourself with the exact structure, timing, and question types of your exam. Knowing how many questions per section and how much time you have removes anxiety and lets you plan your pacing.

📖 Explain it to someone else

If you can explain a concept in simple terms to a friend or family member, you truly understand it. If you stumble, that's exactly where you need to focus your review.
