I took the Kaplan course
recently and I didn't do that well either. It depends, it works for a few people and for a few it doesn't.
I'll tell you this much that if you have already read the Kaplan
books and PR books, then I wouldn't recommend.I took the course and after that I briefly looked at the books and it was pretty much the same strategies. So if you don't want to read the Kaplan
books, then go and take the course.
The good thing about the course is that there is a lot of practice material. And you can go and attend the workshops ( though I never attended those). But think about it, you will end up spending $1200 (classroom course) for that course, but you can spend less money and get more practice material. And I didn't get other useful materials like OG, etc. And plus this forum is a golden resource, and I really wish that I had known about this site before.
I personally feel that the course didn't help me that much and I depended only on the course.
I hope it helps.
