Hello,

Home preparation or we can say Revision or Practice  is more than enough to score good marks for any competitive exams. You should have a proper schedule and syllabus that is to be cover you should go through last years paper for knowing the pattern of questions, you should go through atleast 10 sample papers for proper practice. Be focused and set a target of how much you want to achieve, so that you can atleast give your best to achieve near to that target.  The most important thing while writing an exam or while preparing is to be calm and focused. So be calm and don't panic.

Hope this helps you.

All the best for your exams.

Give your best

Thank you!
