SchweserNotes benefits? everything, beginning, carefully

koba

Hi there, I just enrolled in the CFA Level I program. I carefully read what it said in the beginning of the textbook, which is that the only material on the exam will be from the textbook. What I am doing is going line by line and summarizing everything that I think is important. My question: do I need Schweser notes as well if I am doing the summarizing myself? My understanding is that Schweser notes try to answer each LOS statement by summarizing what is in the CFA text. Please tell me if anyone only used CFA textbooks or if you think Schweser will help me to succeed on the exam?
Thank you All!
