📖 SAT Reading & Writing Medium
Which choice completes the text so that it conforms to the conventions of Standard English? Among the poems that he wrote during his lifetime, Bashō’s 1686 haiku “The Old Pond” is his most well known and is, arguably, the best haiku of all time. _________ was inspired by nature: it describes the splashes a frog makes after it jumps into a pond.
  1. A. feeling
  2. B. have feeling
  3. C. will felt
  4. D. felt ✓
Explanation: “Felt” is the only option that maintains the past tense verb use in the sentence as seen in the other verbs “depicted” and “used.”
🎯 GMAT Prep Medium
In the number above, which of the following two digits are identical?
  1. A. The tens digit and the hundredths digit
  2. B. The ones digit and the thousandths digit
  3. C. The hundreds digit and the tenths digit
  4. D. The thousands digit and the tenths digit ✓
  5. E. The thousands digit and the hundredths digit
Explanation: The question asks to identify identical digits in a specific number, which is implied to be 5,432.154 based on the correct answer choice. In this number, the thousands digit is 5 and the tenths digit is also 5, making them identical. Choices (A), (B), (C), and (E) are incorrect because they pair digits with different values; for instance, the tens digit (3) does not match the hundredths digit (4). Therefore, only option (D) correctly identifies a pair of matching digits.
⚛️ AP Physics C Hard
A point charge + Q is located at a fixed distance from a sphere. Compare the magnitude of the attractive force on the sphere if the sphere is (1) metal with net charge − Q , (2) metal with no net charge, (3) an insulator with net charge − Q , or (4) an insulator with no net charge.
  1. A. charged metal = charged insulator > uncharged metal = uncharged insulator
  2. B. charged metal > charged insulator > uncharged metal > uncharged insulator ✓
  3. C. charged insulator > charged metal > uncharged insulator > uncharged metal
  4. D. charged insulator > charged metal > uncharged metal = uncharged insulator
  5. E. charged insulator = charged metal > uncharged metal > uncharged insulator
Explanation: The attractive force is strongest for the charged metal sphere because induction causes its free charges to redistribute, creating an internal electric field that pulls the point charge closer than it would be otherwise; this effect is absent in insulators where charges are fixed. For uncharged spheres, the metal experiences a net attraction due to polarization (separation of positive and negative charges), whereas the uncharged insulator experiences zero net force because its uniform charge distribution creates no induced dipole moment. Therefore, the ranking places charged metal first, followed by charged insulator (which attracts via Coulomb's law but lacks induction), then uncharged metal (attracted via polarization), and finally uncharged insulator with no force.

SOCIAL SCIENCE: Passage A is adapted from the 2015 Time Magazine article "What We Can Learn From Coca-Cola's Biggest Blunder" by James C. Cobb. Passage B is adapted from the 2007 Washington Post article "The Flop Heard Round the World" by Peter Carlson. Passage A by Peter Carlson Passage B by James C. Cobb If advertisers for New Coke had used tactics similar to those used to promote the Edsel, they would most likely have:
  1. A. run ads promoting a new secret formula but not allowed anyone to taste it until the day it was launched. ✓
  2. B. kept the launch day of New Coke a secret until its unveiling.
  3. C. limited the number of ads promoting New Coke.
  4. D. promised that it would improve upon an old formula.
Explanation: The Edsel was marketed with excessive hype and secrecy, including promotion of its unique features without allowing consumers to experience them firsthand until launch. Similarly, New Coke was introduced with much fanfare about a new secret formula but faced backlash partly due to lack of consumer input and testing. Thus, using similar tactics would involve promoting a new secret formula without prior tasting.
💻 AP Computer Science A Easy
The following shuffle method is used to shuffle the cards in the Deck class.
  1. A. Replace Line 3 with
  2. B. Replace Line 3 with ✓
  3. C. Replace Line 3 with
  4. D. Replace Line 5 with
  5. E. Replace Lines 7 – 9 with
Explanation: If k starts with the value NUMCARDS , the method encounters cards[NUMCARDS] on Line 7 and throws an ArrayIndexOutOfBoundsException .
🧬 AP Biology Easy
Which sequences in bacterial operons are noncoding sequences?
  1. A. operators and promoters only ✓
  2. B. operators, promoters, and genes for regulatory proteins
  3. C. operators, promoters, and genes for structural proteins
  4. D. promoters, genes for regulatory proteins, and genes for structural proteins
Explanation: In bacterial operons, the operator and promoter are noncoding regulatory sequences that control gene expression but do not code for proteins themselves. In contrast, genes for both structural proteins and regulatory proteins are coding sequences because they contain the information needed to synthesize polypeptides. Therefore, only the operators and promoters fit the definition of noncoding sequences within this context.

💡 Study Tips

🎯 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%.

💚 Sleep is a study strategy

Your brain consolidates memories during sleep. Reviewing material before bed and getting a full night's rest is more effective than staying up late to study. Aim for 8-10 hours before exam day.
