Hello Aspirants,

Hope you doing well, Basically i would say whether you choose jd lee or any other you should focus on them by whom your concept get cleared and your doubts too try to spend more time in self study because if you are not implementing your concept till then you would never learn 100% of that concept

if you wanna know more about the preparation or tips or tricks then i would suggest you to go over this site you will get almost all the information and some additional  information's too
