It is very important to get into that mindset of studying before exams. Your brain needs to get that sincere state of mind to allow you to dedicate yourself to studying. Hence, during examinations, try not to let your mind be distracted and disturbed by anything. You can watch TV or play your favourite video games but during a specific time.

Make a time table for that too. You can study the whole day and have a recess period of 2 hours after studying, preferably at night before you go to bed. Eating and sleeping sufficiently before exams are very necessary for your body. Eat your food on time and sleep on time. Do not compromise on sleep or go to bed late just the night before your exam. This can cause severe headaches in the morning, potentially making you fall sick while writing your exam. Take proper food with a balanced diet plan so that both your body and mind are healthy.

Lastly, do not take too much pressure. If you are having a problem with any chapter, just get help from Vedantu. Do not stress too much and take short breaks in between study hours.

When the bus accelerates and moves forward, it acquires a state of motion. However, the luggage kept on the roof, owing to its inertia, tends to remain in its state of rest.

To avoid this, it is advised to tie any luggage kept on the roof of a bus with a rope.
