📖 SAT Reading & Writing Medium
The student wants to underscore the time period during which Ibn Battuta conducted his exploration. Which choice most effectively uses relevant information from the notes to accomplish this goal? While researching a topic, a student has taken the following notes:
  1. A. Ibn Battuta traveled as far east as China and as far west as Morocco.
  2. B. Many rulers and merchants valued Ibn Battuta’s impressive academic background.
  3. C. During his travels, Ibn Battuta used his personal charisma to make connections.
  4. D. Ibn Battuta travelled through much of the world during the 1300s. ✓
Explanation: The student wants to emphasize the time period when Ibn Battuta travelled. Choice (D) is the only option that explicitly refers to the time when he made his explorations—the 1300s. The other options use information from the text but do not mention the time.
📊 SAT Math Hard
Table: Number of vehicles owned | Number of Company A employees | Number of Company B employees 0 | 2 | 5 1 | 8 | 4 2 | 12 | 15 3 | 3 | 1 20. Two companies each randomly selected 25 employees and asked each of them how many vehicles they own. The results are shown in the table above. If there are a total of 575 employees at Company A and 825 employees at Company B, which of the following statements is most accurate?
  1. A. The total number of employees who own 3 vehicles at Company A is expected to be 2 more than at Company B.
  2. B. The total number of employees who own 3 vehicles at Company A is expected to be 36 more than at Company B. ✓
  3. C. The total number of employees who own 3 vehicles at Company B is expected to be 36 more than at Company A.
  4. D. The total number of employees who own 3 vehicles is expected to be equal at the two companies.
Explanation: Getting to the Answer: For Company A, the ratio of total to sampled employees is \frac{575}{25}=\frac{23}{1}. The ratio for Company B is \frac{825}{25}=\frac{33}{1}.
✍️ AP English Language Easy
The writer wants to add a phrase or more at the beginning of sentence 5 (reproduced below), adjusting for capitalization as needed, to develop the idea introduced in sentences 3 and 4.
  1. A. (as it is now) ✓
  2. B. Then, there is
  3. C. In addition to that, comes
  4. D. Secondly,
  5. E. Among still others, there is
Explanation: All the additional words and phrases are superfluous, adding verbiage but no substance to the list. As written, each of the “contradictory legacies” is stated clearly and economically.
🧬 AP Biology Medium
Which of the following processes does NOT release carbon dioxide?
  1. A. glycolysis ✓
  2. B. oxidation of pyruvate
  3. C. Krebs cycle
  4. D. alcohol fermentation
Explanation: Glycolysis breaks down glucose into two molecules of pyruvate without producing carbon dioxide as a byproduct. In contrast, the oxidation of pyruvate and the Krebs cycle both release CO₂ during their respective reactions, while alcohol fermentation releases CO₂ when pyruvate is converted into ethanol. Therefore, glycolysis is the only process listed that does not generate carbon dioxide.
⚛️ AP Physics C Medium
Consider a mass falling toward Earth as gravitational potential energy is converted to kinetic energy. Which of the following statements is true?
  1. A. The mass and Earth experience equal and opposite accelerations.
  2. B. The change in Earth’s velocity is greater than the change in the mass’s velocity.
  3. C. The mass and Earth experience equal forces.
  4. D. The kinetic energy of both the mass and Earth increase by the same amount.
  5. E. The increase in the kinetic energy of the mass is greater than the increase in Earth’s kinetic energy. ✓
Explanation: 8. (E) In choice (A), Earth and the mass experience equal and opposite forces . Using Newton’s second law, | F | = m _{1} a _{1} = m _{2} a _{2} , we see that because Earth has a greater mass, the magnitude of its acceleration is smaller. In choice (B), since the mass has a greater acceleration (as discussed above), it will have a greater change in its velocity. In choice (C), the mass and Earth experience forces that are equal in magnitude but opposite in direction. In choices (D) and (E), the mass and Earth experience forces with the same magnitude. Based on the equation for power, P = F · v , the rate at which the gravitational force increases the kinetic energy is larger for the mass because it has a greater velocity parallel to the force.
🎓 GRE Prep Hard
Many know him for his great scientific achievements, but Benjamin Franklin always believed that public service should (i) science. Accordingly, his political contributions to the formation of the United States were (ii).
  1. A. impede ✓
  2. B. replicate
  3. C. outweigh
  4. D. substantial
Explanation: The sentence structure "always believed that public service should (i) science" implies a contrast between Franklin's scientific fame and his actual belief about the role of politics, suggesting he felt political duties were more important than research. The word "impede" fits this context because it means to hinder or slow down, indicating that Franklin thought serving the public would necessarily take precedence over, or interfere with, his scientific work. Consequently, his political contributions are described as "substantial," meaning significant and impactful, which aligns with the idea that he dedicated himself fully to public service rather than science.

💡 Study Tips

📖 Use flashcards for active recall

Flashcards work because they force retrieval practice. For best results, shuffle them each session, separate cards you know well from ones you don't, and review the difficult pile more often.

🎯 Eliminate before you guess

On multiple-choice questions, crossing out answers you know are wrong before guessing dramatically improves your odds. Even eliminating one option on a four-choice question raises your chance from 25% to about 33%.
