I should study hard for 2 month how many hours i should study per a day? and how many hours to sleep?

well first of all study towards the night when you do that you remember more so study about 2 to 3 hours and get at least 8 to 10 hours of sleep that way when you go to study again you will be welll rested and then eventually you will get used to your routine.

try this. after u had any lessons start revision the day's lesson for 3 to 4 hours. if u have some free time after that go for a walk while trying to remember a topic. sleep early. set ur alarm to 3 a.m in the morning. this is the time when ur brain is very easy to remember things. u will feel very sleepy at this time so drink some coffee. study for as long as u like and try to make some small notes that u can put inside ur pocket so u can read it every free time u have. if u are creative, make some mind-maps on what u learn. make it colorful. u will remember it faster. concentrate on what u study. and the final one, keep everything in it's place so u can reach out any references in just a short time. hope this helps. :)
