Thorough review is critical to the learning process and for most people should take a significant amount of time (and effort!) potentially equally or surpassing the amount of time taken to do the question set.
- Redo questions that you got wrong or struggled on without looking at the answers or explanations. Think. Rethink. Push yourself. Put pen to paper. Don’t review with only your eyes!
- Once you’ve solved or if you aren’t able to solve in about 10 minutes carefully review the explanation (if provided). Again, put pen to paper and redo the question along with the explanation.
- If we haven’t provided an explanation or if our explanation didn’t clear up your doubts google the first few words of the question and confirm the solution on the GMAT forums.
- Except for CR and RC, take a screenshot and add it to your dropbox review folder so you can easily revisit the question when assigned review in your HW schedule.
- Bring questions that you still find difficult to QA or to our sessions. For sessions add the screenshots to the “review in session” folder in your dropbox.

They can, thus, be taken orally.
The statements above most strongly support a claim that a research procedure that successfully accomplishes which of the following would be beneficial to users of protein drugs?CorrectIncorrect

Question 10 of 10
Products sold under a brand name used to command premium prices because, in general, they were superior to nonbrand rival products. Technical expertise in product development has become so widespread, however, that special quality advantages are very hard to obtain these days and even harder to maintain. As a consequence, brand-name products generally neither offer higher quality nor sell at higher prices. Paradoxically brand names are a bigger marketing advantage than ever.
Which of the following, if true, most helps to resolve the paradox outlined above?CorrectIncorrect
