📝 Questions

📖 SAT Reading & Writing Medium
The student wants to suggest a low-tech way of implementing a sustainable agricultural practice. 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. Factory manufacturing of silt traps can prevent river pollution.
  2. B. When two companion plants are grown near one another, they both benefit. ✓
  3. C. Scientists should utilize gene editing to decrease fertilizer waste.
  4. D. Stover mulch can potentially be turned into renewable biofuels for transportation.
Explanation: While there are many ways that sustainable agriculture could be implemented, the student wishes to suggest a way of doing so that does not involve much technology. The last bullet point suggests that simply planting crops close to each other will increase their success, making (B) the most logical answer. The other options all involve more high-tech ways of implementing sustainable agricultural practices.
🧪 AP Chemistry Medium
Regular tetrahedral molecules or ions include which of the following?
  1. A. SO _{2}
  2. B. NH _{4} ^{+} ✓
  3. C. XeF _{4}
  4. D. ICl _{4} ^{–}
Explanation: B —One or more Lewis structures may help you. A is an irregular tetrahedron (see-saw); C and D are square planar.
💻 AP Computer Science A Hard
An Insect class is to be written, containing the following data fields.
  1. A. age
  2. B. nextAvailableID ✓
  3. C. idNum
  4. D. position
  5. E. direction
Explanation: A static variable is shared by all instances of the class. “Static” means that there will be just one memory slot allocated, no matter how many Insect s are constructed. All instances of Insect access the same information stored in that slot. When an Insect is created, it will get tagged with the current value of nextAvailableID for that memory slot, which will then be incremented for the next Insect created. All of the other variables— age, idNum, position, direction —are specific to one instance of Insect and should therefore be private instance variables in the class.
📊 SAT Math Easy
The linear function g can be written in the form g ( x ) = mx + b , in which m and b are constants. If g (1) = 7 and g (3) = 11, what is the value of m ?
  1. A. −3
  2. B. −1 ✓
  3. C. 2
  4. D. 6
Explanation: The value of m is equivalent to the slope of the function. Since g (1) = 7 and g (3) = 11, use the ordered pairs (1, 7) and (3, 11) to calculate the slope of the line:
✍️ AP English Language Hard
The speaker’s rhetorical intent in the first sentence of the passage (lines 1–3) is made evident by all of the following EXCEPT
  1. A. to convey a sense of authority.
  2. B. to make a connection with his audience by saying “we” and “us.”
  3. C. to assure his audience that he’s attuned to their beliefs and values.
  4. D. to acknowledge that they are people of some stature.
  5. E. to capture the audience’s attention using hyperbole. ✓
Explanation: 12. (E) The speaker’s intentions are made clear by his self-assured tone, the allusion to “advisers,” the use of first-person pronouns, and the phrase “no doubt.” To win the confidence of his audience, he may deliberately be avoiding hyperbole or other unsettling rhetoric.
🎓 GRE Prep Medium
Mount Godwin-Austen, more commonly known as K2, is the second highest mountain in the world, with its peaks reaching more than 28,000 feet high.
  1. A. famous ✓
  2. B. bombastic
  3. C. critical
  4. D. prolific
  5. E. eclectic
Explanation: The sentence describes K2 as 'the second highest mountain in the world, with its peaks reaching more than 28,000 feet high'—a description that emphasizes its fame and recognition due to its extreme height and status. 'Famous' fits best as it means widely known, which aligns with K2's renowned status among mountaineers and the public. The other options (bombastic = overly dramatic, critical = essential or judgmental, prolific = productive, eclectic = diverse) do not describe the mountain's renown.

💡 Study Tips

📖 Teach concepts using diagrams

Drawing concept maps, flowcharts, or diagrams helps you see relationships between ideas that aren't obvious in linear notes. This approach works for everyone and strengthens conceptual thinking.

🎯 Use process of elimination on science questions

On AP and standardized science sections, you can often eliminate choices by checking units, order of magnitude, or whether the answer makes physical sense — even before doing the full calculation.
