after all the stuff allegation i want to say that on this topic
In my view best study time is………
1. When you can study without being disturbed.
2. When you are not tired and sleepy.
3. When you think you can complete your target.
4. When you can concentrate.
5. Study time depends on the fact that is it easy for you to recall things studies at night orstudied at morning. Plan your study accordingly, what is important is output.
Personally I prefer study at night b coz during my PCC I studies for 3 month entire night and sleeps for 2 hour in after noon time because I felt that the afternoon time (between 1.30 to 4.30 pm) is not productive as better to sleep and study at night. Even my exams are over but I made a habit to study till 4.00am every day.
Elder has said that morning study time is better, but I think it is better to study whenever you wants, rather then concluding best time of study.
Remember study at day or night by maintain your minimum study hours.
