I took it two or three weeks ago.
I used kaplan anywhere...they were having a sale at 100 off. if you're self motivated but need guidance this is a good option. i studied for about 2 months and it worked fine.
My husband just bought a few books and studied off and on for a month and did great.
It all kind of depends on you. You know more then anyone else about how much prep you will need to do. ETS Home
has a sample test for free..should give you a good feel
