I have it- its is really hard almost LSAT like and has a lot of typos but I think it is good practice
Yes, I also got the same feeling. Earlier, I was practicing questions from GMAT club forum. But, somebody suggested in his debrief that it is not recommended to use those questions because they may reappear during practice tests and make my score unrealistic. So, I started using RC 99, but as soon as I hit few question my confidence toppled down.
I was doing fairly well on GMAT club forum, but on RC 99 most of the answers I am getting are wrong. Even explanation is not too convincing.
It seems as if this book is not true representative of GMAT RC question. But the problem is, if not this book then which one to pick up.
Any suggestions, from where we can practice RC question which are nearer to real GMAT.
