Which question bank is better IFT or Qbank by Schweser for CFA L1?
Consider Apptuto for L1: great mobile app, great quality questions (in hindsight was great practice for the real exam), and great price. They’re also an approved prep provider. Best of luck!
Haven’t used the other two you mentioned so I can’t speak to their quality.
