FRM books or Third party books (Schweser, BT)

Guys, I’ve been trying to find some posts regarding the materials to use for FRM Part I. But I can’t find concrete answers.

I’m planning to take it on November and I’m just wondering if I should get the books from GARP or from third party providers such as Schweser and Bionic Turtle. What would be the advantages and disadvantages of such?

If this has been discussed before, I would appreciate if you can direct me to the thread.

Thanks!

I used Schweser online study and passed. The GARP books are not as good at highlighting the important bits, ie they are quite verbose.

Schweser online QBank is good too
