45 SECs
IMO A
2/3 Split.
determine v/s determinining
so down to A and C
again there is a split
help vs helps
differences....help

C is passive and differences ...helps is wrong

So A

GMAT score is equally counted as your GPA and 78 clicks can change you life.

Since "subtle differences" is plural, "help" is the right usage. Option C and D eliminated.

between should be used only when you compare 2 things with an "and".
Here we are not saying "A and B". Thus, "differences in" is the right usage.

B is incorrect because it is not the difference in 2 ears.....B is eliminated

Thus, Choose A.

"Target Test Prep is the closest to the official version of the GMAT exam, about 99% accuracy in terms of the quality and quantity of information. The course has excellently created singular sets of focused lessons and tests for every possible topic that one could come across in the official GMAT exam."

"The TTP course maximizes the efficiency of the time you spend studying. It will take time and effort but I could almost guarantee that if you complete the course exactly as it is laid out you will get an amazing score. They also have a very responsive team willing to help with any questions you might have."

"TTP has two things that I think no other test prep company offers: A teaching approach that reinforces understanding and an attitude that will give you the mental preparedness needed to succeed on the test. TTP gives you a deep understanding of the concept you need to know while teaching you how to think."
