Hi.
I am reading from CFAI material (at cruising speed as it is rather early) as I know even closer to the exam (say 2-3 months before this), I won't be able to commit more than 2 hours a day (and maybe 4 during weekends); this is due to due to workload at office, kiddos etc.
I am making notes, doing EOCs and I intend re-reading chapters and leaving aside significant time for revision closer to exam.
Although material from CFAI books is big, I think it has a number of examples which strengthens my understanding.
Do you know of people who had (seriously) studied from the CFAI books and failed?
Thank you all.
