Try to have a decluttered and organised space for studying. Having a neat surrounding helps you avoid distractions and be focused.

Try to organise a group study session from time to time as it helps clear doubts and also gives you an opportunity to teach your friends and revise. 

Some students sacrifice sleep for exams, but your body demands a good night's sleep for a well-rested mind. An 8-hour sleep is essential for good memory and concentration. 

Keep your body and mind healthy with a balanced diet as it improves immunity and nutrients are required for fighting fatigue, sleepiness, and lack of concentration.
