GRE Test Prep Companies

Can anyone recommend me a good GRE test prep company? Is Kaplan good?I plan on taking it in October the GRE

you should check test prep materials before looking for a test prep company, it’s just a personal opinion.

@Mrduque any recommendations? I have 800+ most used words for the GRE by princeton review along with the ETS Books.

@94dino I would only recommend test prep material from the ETS itself, are you aiming for an specific score?

I am aiming to apply to a PhD program from undergrad so the best possible score i could get. If i could get around 320 it would be great!
