Hi everyone
I finished doing all the questions on the OG 12th and now I've purchased OG quant review 2nd edition. I'm wondering which questions in the book are unique, compared with those in OG 12th. I know there are many common questions between the two books and I'm looking to concentrate only on the unique questions of OG quant 2nd edition. If you know about it, please let me know.
Thanks a lot!
