Class 11

Talk to your parents and teachers about this and explain your problem. They know you better and will tell you proper solutions. The only thing I can recommend against distraction is to cut off from Internet, phones and TV and restrict your social time. Envision your goal, imagine your life with and without it, commit to it and start acting for it. To be honest you only lack motivation. If you really want to crack JEE then give yourself a reason for it.

Yes, you can apply. You just have the clear the entrance exam.

If you want to pursue further education in the field of commerce then firstly you should put your all focus on your 11th and 12th syllabus, why I am saying is this because whatever you are going to do next is 90% based on your 11th and 12th syllabus. If you want to get your hands on something professional, then you can think about CA CS CMA and even ACCA which I think is the most easy professional course available for commerce students out there.
Best of luck.

Your class 11th marks will not be considered while calculating your GPA or CGPA. only class 12th marks will be considered.

No, class 11th scores are not seen in GPA. Only class 12th standard scores will be considered. All the best for your bright future.

You can't choose the college on your own. You have to secure a good rank in JEE Mains to choose.

Hi!
Yes, you can. Most universities have a provision for scholarships. You will have to check their websites individually as each university has a different criterion.

You have to pass class 12th, and then apply for NIMS. You can do fashion designing jewellery design. Pearl Academy also avails such courses. You can also do BFA. Till now, focus on your studies to get good marks. Regards.

By preparing your class 11th and class 12th syllabus thoroughly. Depending on your capabilities, you may have to pursue a coaching later. The best way to prepare now is to focus on your Physics, Chemistry and Maths. Prepare them as you would prepare for IIT. Because, the syllabus is same you will score better marks in your class 11th and as well in JEE.
