I hope you are talking about CFA exam cause your name has some other exam (lol).
Yes. Complete coverage of Schweser notes (including practice exam booklets) + official website’s online chapter-wise tests and mock tests will be enough to pass Level 1 and Level 2.
For level 3, additionally solving past exam papers for AM sessions is a must.
I wouldn’t recommend only using the Schweser notes; you should make sure you are answering all of the blue box questions in the CFAI readings and the end of chapter questions from the CFAI materials as well.
