I guess it depends, do you want just to pass the exams or do you want to know the planes as well?
You could use one the famous "multiple question database online", where you can memorize each question and apparently are the same than in the exams. Will you learn anything at all doing this?
If you really want to learn, it will take you at least ¿6 months? each part, which is what i am doing, year and a half in total.
I am doing distance learning, first exams in August, full time job, and have to study around 15 hours per week to get everything done one time. There is a high work load, reading all the chapters, answering questions, test practice...
It will take me a bit longer than for those who just memorize test, but being a good pilot, the vocation of my life, starts here. Does anyone disagree?
It´s up to you
