just read wht's going to taught that day in morning

after school learn and revise , you will be more confident  

You are in Second Shift , Wake up early and give time to difficult subjects before going to school, after coming back just revise what you have done  in morning and then give time to little bit easy subjects

Yes, you can attemp any question first or last. Try those questions first about which you are sure.

Urdu is a subject but not in schools ....... Who has interest in Urdu so,, they were go to Urdu tuition ....the answer of your question is yes,,,but not in India..

thanks man. ....

You can use any type of pen in your board exams just make sure that it has a good grip on your hand and helps you to maintain speed. 

It should not leak as it will only waste your time. It should run smoothly. No need to use multiple pens. Write the heading and underline it. 

Do the paper with one kind of pen only and do not use red or green pens. Also, make sure that you carry two extra pens with you in the examination hall. 

All the best! 

Yes, going to washroom is allowed during board exams but I would advise you to use the washroom once before the examination starts. 

Why waste any minute of your crucial three hours of exam?  Concentrate on your paper thoroughly and maintain the speed. 

In case,  you want to urgently use washroom you can take permission from the invigilator and go. 

All the best! 

Yes, after clearing the JEE mains exam you will have to get yourself registered for JEE advanced.  

Please go through their website once and read the circular / prospectus they have released. You will get the best information and correct too from there. 

All the best! 

No, nothing like this is permittted in boards. If you want to mark the headings or the important points write them with a black pen.

Although, it is highly advised to use only blue pen in paper and underline all the headings with it in order to complete time. Your answers are more important than your presentation. Write in clear handwriting and underline the important points.

All the best!

No, nothing like this is allowed in examination hall. Log /sine tables are provided in the hall. Only carry your complete geometry box with 2-3 extra pens and a water bottle.

All the best !
