reading method

I am not understanding one thing that, i have to memorize all things or just go through all topic by understanding all. what is the process of reading means, only understanding all / memorize / just reading ? I just started reading for level-1, June-2018, it is possible to pass at first attempt as i started now?

Bleron did in under a week

You will hear this again and again if/when you progress through exams:

You can’t memorize your way to a CFA Charter. Don’t try to memorize all of the formulas, many are special cases or approximations.

Believe me. I finished in 18 months.

You have plenty of time for level 1. As long as you don’t take it too lightly it will be no issue. Just do the readings then a bunch of practice problems and you’ll be fine. A lot of people sitting for level 1 do little or no studying and skew the pass rates down.
