CFAI Mock Test

Hi guys, I’ve done a few mock test from the CFAI website and found that many of the questions are repeated.

My question is, is it useful to keep drilling the CFAI mock questions or should I try questions from other providers?

I am just worried that I am not exposed to wider range of question bank, since I keep getting the same questions.

The big day is coming real soon and I hope to get some input from here. Thank you and all the best everyone!
