Although
MGMAT SC is a great book, it did not work for me. As someone has suggested, buy the SC Grail and go through it. This book does a great job at explaining the basics. I used the SC Grail and then went through the first few chapters of
MGMAT SC book, noted down some rules such as the use of like v/s as etc. Then I targeted the IG questions directly, the learning that I got from the OG explanations was unmatchable to any book, including the
MGMAT SC book . Ofcourse, this is what worked for me

. I have no idea about the powerscore verbal book though , the powerscore CR book is phenomenal !!!!
Good luck !
