Effort required to pass Level 1 given my background? next, first, currently, management, background

clearlycanadian

I will complete my MBA in Corporate Finance/Investments/Accounting this Spring (first week of May) from NYU Stern. I am going part-time, and currently work in asset management risk.
I am on the fence about possibly taking the exam in June. I really don’t want to have to deal with my last semester of classes and the CFA at the same time, so I am more leaning towards taking it next December. I figure I graduate in May, will take off the rest of May, June, and July (since I haven’t had a summer the last 2 summers), and then begin studying between August/September.
I just wanted to see if anyone on here followed a similar path to mine, and if so, how hard level 1 was for you after doing a (strong) MBA in Finance/Accounting? I know Levels 2 and 3 are insanely difficult, and after doing almost 3 years of night school (come May), I’m trying to ration out my energy/sanity as best as possible, since I know I will need to basically devote my life to Levels 2 and 3.
Any advice would be greatly appreciated - thank you!
