Hi, it depends on your body clock and when you feel most alert.

Hello Lion, In the early morning or in general after a good sleep and when you have not eaten too much. When your mind is clear and you are not upset you can concentrate more and learn easier. Whenever you feel like learning, just seize this time to do it. Learning the same subject for longer times makes it tedious. So studying a certain subject at intervals where various subjects are alternating each period of time makes it more fun and you are more able to acquire the learned material.

I like to go to sleep at 10PM, set my alarm for 2AM, study until 3:30, then go back to sleep. This is the ABSOLUTE BEST way to learn!
