📝 Questions

✍️ AP English Language Medium
That the speaker declares that some dreams “are so imperatively significant, so vitally important” (lines 26–27) is ironic mainly because
  1. A. the speaker has been railing against the telling of dreams. ✓
  2. B. some dreams are “exceptional” (line 26).
  3. C. the speaker has characterized dreams as “intensely personal” (lines 15–16).
  4. D. irrational events occur in dreams as well as in reality.
  5. E. people rarely remember their dreams.
Explanation: After criticizing people for imposing their dreams on others, it is ironic that the speaker is about to do just what he insists should not be done—tell the story of a dream.
🎓 GRE Prep Medium
Quantity A (r + 3)(s + 2) Quantity B rs + 12
  1. A. Quantity A is greater.
  2. B. Quantity B is greater.
  3. C. The two quantities are equal.
  4. D. The relationship cannot be determined from the information given. ✓
Explanation: Quantity A expands to rs + 2r + 3s + 6, while Quantity B is rs + 12. Subtracting rs from both gives Quantity A: 2r + 3s + 6 vs Quantity B: 12. Without knowing values of r and s, the relationship is undetermined—for example, if r = 0, s = 0, then A = 6 < B = 12; if r = 3, s = 2, then A = 6 + 6 + 6 = 18 > B = 12.
🧬 AP Biology Medium
A plant cell with a solute potential of –4.0 bars and a pressure potential of 0.5 bars is placed into a solution with a water potential of –5.0 bars. What will happen to the plant cell in this solution?
  1. A. Water will flow into the plant cell because the plant cell has a total water potential that is lower than that of the surrounding solution.
  2. B. Water will flow into the plant cell because the plant cell has a total water potential that is higher than that of the surrounding solution.
  3. C. Water will flow out of the plant cell because the plant cell has a total water potential that is lower than that of the surrounding solution.
  4. D. Water will flow out of the plant cell because the plant cell has a total water potential that is higher than that of the surrounding solution. ✓
Explanation: First, calculate the plant cell's total water potential by adding its solute potential (–4.0 bars) and pressure potential (0.5 bars), which equals –3.5 bars. Water always moves from an area of higher (less negative) water potential to an area of lower (more negative) water potential; since –3.5 is greater than the surrounding solution's –5.0, water will flow out of the cell into the more concentrated external solution. This process causes the cell to lose water and become flaccid.
⚛️ AP Physics C Easy
The magnetic field created by the two wires shown at point A in the figure is B _{0} (pointing out of the page), and the two wires carry identical currents in the same direction. Which of the following is true?
  1. A. Both wires carry a current of 4 π d /3 μ _{0} toward the top of the page.
  2. B. Both wires carry a current of 4 π d /3 μ _{0} toward the bottom of the page.
  3. C. Both wires carry a current of 4 π dB _{0} / μ _{0} toward the top of the page. ✓
  4. D. Both wires carry a current of 4 π dB _{0} / μ _{0} toward the bottom of the page.
  5. E. It is impossible for the wires to produce a magnetic field pointing perpendicular to the page.
Explanation: Each wire produces a magnetic field at point A given by the Biot-Savart law for a long straight wire, $B = \frac{\mu_0 I}{2\pi d}$. Since the currents are identical and in the same direction, the fields add constructively. The total field is $B_0 = 2 \left( \frac{\mu_0 I}{2\pi d} \right) = \frac{\mu_0 I}{\pi d}$. Solving for the current yields $I = \frac{\pi d B_0}{\mu_0}$.
🧪 AP Chemistry Medium
A 0.1 molar solution of acetic acid, CH _{3} COOH, has a pH of about:
  1. A. 1
  2. B. 3 ✓
  3. C. 7
  4. D. 10
Explanation: B —Any acid will have a pH below 7; thus, C and D can be eliminated. A 0.1 molar solution of a strong acid would have a pH of 1. Acetic acid is not a strong acid, which eliminates A.
💻 AP Computer Science A Medium
Which of the following is a false statement about the methods?
  1. A. equals, lessThan , and toString are all accessor methods.
  2. B. increment is a mutator method.
  3. C. Time() is the no-argument constructor.
  4. D. The Time class has three constructors. ✓
  5. E. There are no static methods in this class.
Explanation: There are just two constructors. Constructors are recognizable by having the same name as the class, and no return type.

💡 Study Tips

💚 Stay hydrated during study sessions

Even mild dehydration can reduce concentration and short-term memory. Keep a water bottle at your desk and take a sip during each break. Your brain is mostly water — it needs fuel to perform.

📖 Start with the hardest topic first

Your mental energy is highest at the beginning of a study session. Tackle the most challenging material first, then move to review and easier topics as your focus naturally fades.
