So I am not alone:)
Currently I am reviewing my undergraduate notes for I have a comprehensive exam in mid March in my school that covers almost 70% of the GRE exam. I also ordered the ETS book: Practicing to take the GRE chemistry, but I wonder if I will receive it on time.
I have a couple of papers from ETS, the one they offer online and another one I found available online as well....
There are few books you can review online for free that could help, but I am not sure about their creditability.
I also referred to a website for 'chemical olymiad' where you can comprehensive questions with solutions. oecho.at
This could be helpful.
Good luck.
Please let me know if you need anything and I appreciate any advice you may provide.
