Shiksha.com has collated some helpful preparation tips that students can follow to do well in their upcoming Class 12 board examination:

1. Follow a proper schedule. Sleep early and wake up early in the morning, have a proper breakfast, and then sit to study. Do not stay up late at night. Take out an hour or two to relax and not think about the exams during the day. Read, sleep, play, or do whatever you think diverts your attention away from exams. Munch on healthy food while you study. Junk food is a big no.

2. Do not have too much on the plate. Constructively exercise your brain, and do not burden it with a lot of thoughts. Set realistic targets for the day. Do not try and study everything in a single day. Try taking it slow and apportion the revision accordingly. Of the 5 or 6 subjects, pick up 2 or a maximum of 3 subjects and pick up a topic or two from each and go into the depths of the topics, instead of skimming 8-10 topics.

3. Mix and match Plan the day well. Do not have all easy subjects/topics in a day or do not overburden with topics that you find difficult. To maximize the output, start with a light subject for an hour or so, and then take up a heavy subject or a topic.

4. Solve sample papers. Practicing sample papers makes one familiar with the exam pattern, marking scheme, and the different types of questions asked.

5. Practice the art of relaxatio.n Exercise and meditation help improve concentration. Meditation strengthens the mind, it comes under control and is able to provide effective guidance to the physical body to effectively execute all its projects. Psychological Exercises are a powerful way of improving concentration and improving mental strength. During exam time, the aim of a student should be to perform to the best of his/her abilities and also concentrate on keeping themselves healthy, and relaxation exercises will help him/her do that.
