Welcome to the gmatclub sandeepkumarkg!
Are you using Manhattan GMAT SC
guide? I think the book is good enough, also you can have a look at Veritas
SC guides also. Before that you can try gmatclub grammar book.
Hey Thanks ....
I am not using Manhattan...i am using the 11 th edition of OG. Ya i have started using the gmatclub grammar book and its too good.
Please start using Manhattan SC guide, it's bible for SC! Also if you can get an hold on OG12
it would be great! Also, are you using error log
? Error log
is quite helping to figure out where you are lacking.
Anyhow, good luck with your preparation and keep updating us about your progress.
