Is it A. ?
Maya graduated at the top of her class
This means that her average overall grade was highest

I would go in for E.

Reason:
Darise gets : 10, 10, 10 and 8 (Given that Darise scored 10 in 3 classes and was equal to May in 1 one of the four classes). So these score could be her best. This means Darise avg is 9.5
Maya gets: 8,8,8,8 (Given that Maya did not score greater than 8 and we will assume she has got 8 in all four classes). So, these scores could be her best. This means Maya's avg is 8.

Given the above, Darise has better average than Maya.

A is deceiving and gives info that Maya 'graduated' as a topper. But we are in reference to these 4 classes and unsure if these 4 classes are the only classes in the overall curriculum to graduate out of.

Should be E.

I was struggling between D and E. E clearly says D received 10 in three subjects and M didn't score above 8. And M and D got same score in one subject.

If we assume D - 10 10 10 1 then maximum M can have is 8 8 8 1 only.

Pretty sure it's E

(3*10)30 pts+7=37

(8*3) 24pts+7=31

So for sure one is larger than the ther

OA given is a clear B. I picked E also. Thanks for clearing my doubts. E must surely be it. This is in one of the paper tests if any of you is interested in knowing the source. As long as they have these kind of answer keys on the GMAT, I'm cool with that

Guys, what do you think the answer should be for this.

I also thought the answer should be 'E', but OA is different.

B and E both make sense.

But B and E both give different answers.

Also E is much clearer than B.
