Please tell me how should I study for board exam
Here are few tips:
Create a revision timetable. Remember to take regular breaks and get out and exercise.
Rewriting. Rewriting your notes is great if you're a kinesthetic learner. Mind mapping is the most effective way of doing this. Also, when you re-write something, you will probably think about what you are writing, what it's about, and why you wrote it down. Most importantly, it refreshes your memory. If you took notes a month ago and just found out that those notes will be relevant in your exam, rewriting them will remind you of them when you need it for your exam.
Find the right hours. Don't study when you're really tired. It's better to study for two hours in one day than to try and cram in that daily hour of studying at two in the morning. You won't remember much and you're likely to stop before you have studied what you need.
Don't cram. Cramming the night before is proven to be useless, because you're taking in so much information at once that it's impossible to memorize it at all -- in fact, you'll hardly retain anything. I know it's been preached to you many times before, but it's true: Studying before and going over it multiple times really is the best way to learn the material. This is especially true with things like history and subjects dealing with theory.
Subjects. If it's math you're studying for, work on the problems. Don't just read over it like you would for a history class, because you can actually do math, but you can seldom dohistory. Working problems out will help burn them into your mind, and remember: if you can't solve the problem before the exam, you won't be able to solve it on the exam either. If you are studying for a more social subject, do your research! Make sure you know what you're talking about!
Surroundings. How do you study best? In your PJ's, or your favorite t-shirt? With music or without? In your room or outside? Regardless, you probably won't be able to study while there are distractions like:
It's too dark. Your eyes will strain in dim light.
Correct lighting. For men, try studying with a dimmer light (though not overly dim). Statistics say that 75% of study and focus better in a brighter room with little noise.
TV. Some people like to have the TV on quietly in the background. This can cut both ways in that it can distract you from time to time, but also can help you to continue studying. It's a risky strategy to have the TV on: nobody really knows how much it takes away from your attention and may be distracting you more than you realize.
Take Breaks. You need some time to have fun and it is better to revise when you are feeling relaxed than to exhaust yourself studying all day! The only caveat is, you need to avoid procrastination.
Plan: Always create a plan before you start studying, not to mention that this plan has to be achievable. If out of 5 lessons 3 are easy and can be finished fast, finish them first, that way you can spend quality time on the difficult lessons without fretting. Small tricks like these will help you complete your portions quickly.
Review. When you are finished studying one page of your notes, before you move on to the next page, ask yourself questions relating to the material on that page to see if you have remembered what you just studied. It also helps to say the answers to your questions out loud as if you were trying to explain it to someone else.
