You have exactly 112 days until December exam. It took me 4 months to prepare for L1, relying solely on CFAI books and Qbank. That said, I really think you have enough time to complete this either way (CFAI vs Notes, or both). But the answer to your question depends on your individual ability, time schedule, time spent, working hours etc.
Cheers
P.S. Around 80% of AFers have relied only on Notes and managed to pass without a problem.
