Hi everyone!

I'm going to take GRE Math this november.

I use "Cracin GRE Math Subjet Test "(3rd) for my preparation.

Do you know,if is there any difference between 3rd and 4th editions? Importantly, does the 4th edition include any new problems in "Chapter Review Questions " ? Is it worth buying?

Also, I'm new in Abstract Algebra, and I feel that solving only 20 problems from "Cracin..." is not enough to know it inside out.

Can you recommend me a practice book containing SIMPLE (ranging with those of GRE) exercises on Group Theory?

I appreciate any help.

Thanks!
