Q: Is it also good for students to study late at night and midnights?

A: Well, this is a question that has troubled mankind forever. Is it good? Well, as an adult, you need an average of 7 to 8 hours of sleep, minimum per day. If you have not been getting this number of hours of sleep for a while, then the number required daily increases. It’s just a clear case of not being able to cheat nature.
Different students like to study differently. Some prefer the day time, others prefer midnight when it’s dark and quiet. I belong to the first class and the only time I tried to do what others were doing (reading at night) with coffee to boot, I spent all night in the toilet 😀
