Kraev Thanks, Gene! Very helpful session! A couple of questions from my side:
1. Are all problems really on 700+ level? (at least the first 3-4 seemed manageable? Could you evaluate the difficulty of the questions and probably break them down into 700+ and rather 740+ levels? Would those fit in the fiirst group?
2. Regarding Question 6 (Permutations & Combinations) - Is there an exact reason why you started in the first step with 3 & 5, and not 7/8 for example? I would be grateful if you could just shortly elaborate on that!
3. Which are the 6 main error types in SC?
Thank you in advance!
Hi Dimiter, thank you for your questions and apologies for the delay in response.
1) All of the problems covered are questions representative of high difficulty that 700+ scorers would see on Test Day. Yes, the first few questions in the set are slightly "easier", but since the test is adaptive at the question level, in order to get to the highest-difficulty questions, you'll need to be able to answer "low 700" questions correctly. But your hunch is right --- certainly the combinations/permutations question would qualify as a more difficult question than the first three! Speaking of which...
2) It's not mathematically "wrong" to start with 7/8, but it gets more complex, since if you started with 7/8, you'd have to consider three different possibilities: putting a 7 and 8 into two slots, and putting two 7s into two slots, and two 8s into two slots.
3) For sentence correction, the six main topics tend to be: verbs, pronouns, modification, parallelism, comparison, and idioms/usage. The most complex sentence correction questions will test across multiple topics.
Hope this helps! Please reach out to us if you have any further questions.
