Hi! A 760 would be a 715 on the Focus Edition

Here’s a post with more such comparisons - gmat-focus-to-gmat-classic-score-calculator-conversion-419508.html#p3276792

Around a 715 at least^

Nope. But to be fair. I did attempt Q’s from the OG book and one thing I felt was that the Hard Section of the Q’s contained Q’s from easy levels too which felt pretty misleading unfortunately.
FORUM have endless amount of Q’s.

Here’s a setting I used to get OG Q’s.
Note: I set this for you without taking into account topics and Level of difficulty.
Hope it helps.

Hi, I came across this question in the quiz yesterday . Can anyone provide a good explanation :

Harry is planning a journey to Hogwarts. He can go alone or with any number of his 7 friends: Ron, Hermione, Hagrid, Luna, Neville, Fred and George. If Ron and Hermione refuse to go together, how many groups are possible for the journey ?

Harry is planning a journey to Hogwarts. He can go alone or with any number of his 7 friends: Ron, Hermione, Hagrid, Luna, Neville, Fred and George. If Ron and Hermione refuse to go together, how many groups are possible for the journey ?

A. \(88\)
B. \(95\)
C. \(96\)
D. \(1,560\)
E. \(3,600\)


How many groups are possible if we did not have the restriction? Without the restriction the total number of groups possible is \(2^7\): each of Harry's 7 friends can either join Harry or not.

How many groups are possible with Ron and Hermione in them? If Ron and Hermione are in the group, then each of the 5 remaining friends can either join or not, so the number of groups with Ron and Hermione is \(2^5\).

So, there are \(Total-Restriction=2^7-2^5=2^5(2^2-1)=96\) groups possible.


Answer: C

Discussed here: https://gmatclub.com/forum/harry-is-pla ... 65289.html

Hope it helps.

Thank you so much for the quick response Brunel.
I do realise I have a need to strengthen the probability and the ’countint methods’ section of GMAT.
Can you guide or direct to any such resource for 3asy and practical understand of the concepts of the same.
