Hello Vidhyashri , you can give the improvement exam again. You can give it for many time as you want. But from 4 th attempt you have to appear for practical exams also. So male sure to get good marks in this attempt.

If you are doing full time job then, You have to really concentrate more because you get less time to study. Try to do part time job, so that you can get more time to study. As you attempt exams two time , i think you know what to study. I will tell you how to study

You can make use of your smart phone. You can watch vedios to clear your concepts.

Thanks.

Hey,

Stick to NCERT.( Exception: Economics , Commerce students you may follow any relevant books based on CBSE syllabus as NCERT is too vague)
• Read & build concepts via notes.
• Do example questions.
• Exercise questions. (Intext questions incase if chemistry)
• Reference Books (Not mandatory, but do refer for maths as NCERT is not sufficient).
↪ Mark the important questions, different types.
• Practise at least 5-7 years Board papers.
• Do mock tests.
• Revise.

Hope it helps! Comment Down if you have any other queries... Goodluck!

P.S : It doesn't matter how much hours you spent "quantitavely", but it's the qualitative approach that matters!

Well, if you really want to do well, you will have to put in more hardwork, effort and time into it. If your main aim is to score in boards, I would suggest you to solve as much previous year papers as possible. There are a few books which have previous year solved papers. Try going through them and try taking out some time off your schedule.
