Is IFT practice questions and Mock exams are good source or would you recommend another prep provider sources? Noting that I am currently fully reliant on CFAI TT, EOC and BB.
I don’t think any prep provider can beat the regular practice qs of CFAI incl the BB ones. That said there are some quality third party Mocks that are very good and mimic the actual exam. Mocks most certainly you will have to rely on the prep provider and my suggestion would be attempt as many and varied as you can.
