With this much time on your hands I would be hitting QBank going through each of the 18 study session one at a time to identify your weaknesses. If you’re like me you’ll have forgotten the majoriy of the material or are just forgotten the formulas and calcs required. I re-ran through the material a second time going through QBank to guide me. FRA I read 3 times. Just keep rinsing and repeating until you feel comfortable with your QBank scores.
Oh, and with QBank, don’t assume a 70% on QBank means you’re good to go. Untick the easy and medium questions to give you a better idea of where you stand.
With a month to go to the exam, just start hitting the practice exams and go through your mistakes.
For Level 1, I only did one Mock test (the CFAI one). But I took it the morning and evening on seperate weeks, to guage my progress. I found that doing a ton of QBank questions, while not at the same difficulty, gave me a good preparation when coupled with EOCs. I got to the point where I was doing 120 questions a night leading up to the exam, aiming to get 80-85% on the medium and hard questions (unchecked easy). Level 1’s challenge for me was the breadth of knowledge, not the depth or difficulty. At the end doing Qbank tests became a game to me where I had to beat my high score and beat my rolling average in that section lol
