I'm studying Manhattan 9 Strategy guides and after each book, I've planned not to do questions which we're suppose to solve from Official Guides during Manhattan strategy guides study.
After I'm done with all 9 guides then and only I'll study each and everything from Official Guides 3 books.
Is this OK.
