Q bank questions - worth it?

I have been using CFAI books exclusively but want to get more practice questions. I know Q bank has been mentioned a lot on this board - is that the best option? Thanks in advance!

could not survive without it…has over 3800 questions in various level of difficulty…I am about 75% through them and it really helps you get the basics down and so you know what areas to concentrate on

Yes, it is worth it. And yes, it’s the best option.
