Hi,
You need to follow an effective schedule of study. Give proper required time to each subject.
Keep your mind calm, focused and stable.
Do meditation if you get time.
Don't eat such food that makes you sleepy.
Solve and practice the sample papers.
Take proper sleep and diet. Be healthy and don't eat junk.
Try and study early morning time because it is considered as the best time to perceive and concentration.
Prepare notes and study them. Instead of mugging up, just understand the subjects and concepts.

Following all this can help you do better.
Hope my answer helped you!.

No, you can not. B.Ed is compulsory to qualify SET.

Yes you can apply for these tests after completion of the course from NIOS.

Well, firstly you need to decide in which college you wish to take admission and check the criteria for selection. Usually 50% and above is considered. You will have to apply for National Eligibility Test. The National Eligibility Test is to be taken in the subject in which you have expertise and have pursued your Masters Degree program.
