I read in several posts that SC MGMAT is a great book for Non-Native English speakers for conceptual clarity. I just want to make sure that I am picking the correct book. On their website I saw a book with the name MGMAT SC Strategy guide, is this the book everyone is talking about?

Also I really need to pick a book that can tell me strategies for Quant, I am doing very bad in my Quant timings, any recommendations will be greatly appreciated. I do have OG 11.

Cheers,
