Hello Student,

 Well I would just recommend you to go through notes and whatever your teacher just always keep in mind and keep following ,mark all those important point in fact teacher ask you to mark some part as VVI(very very important), so you have just to follow your teacher. If these thing your doubts will be always cleared ,and this is board exam so you have to just to stick to ncert.and one thing more during exam just keep solving unsolved sample paper as much as possible,by setting time, what's happens if you do,

• You should get known to your doubts,with revision ,and also know how to manage time which chapter takes more time ,etc.
• You will rock

Hope this will help you! 

All the best
