Totally depends on your field of interest. You can do B.A. honors, or economics. You need to know what you're good at. And then opt any field carefully, because this will decide your future.

Hi Ajay, Kindly get in touch with the CBSE board or your school about the process to re-apply. They will guide better. And I believe you can even pursue your 12th again from Open Universities as they do have provision for 12th schooling and you don't need to go for regular classes plus the fee is minimal. Kindly try for IGNOU university.

You can easily pursue a BA degree from a local college. The gap and division should affect your admission unless you are applying for big colleges or main campuses. It would be better to pursue it from distance too if you don't want to do regular classes. But I wouldn't recommend that since you already have a 10 year gap and you may need some guidance to study.

Hi,
You can do short term courses for 2 reasons - for hobby or for job or business or long term career. If you are doing along with graduation, you can do in photography, languages, counseling and personality development classes. That will help you have additional skill sets and improve your own attitude.

Fashion Technology is a good course in terms of scope and package. However it doesn't have any much significant outside Fashion Industry. So keep that in mind. If you really want to pursue this course and want to see yourself as a fashion designer in next 10 years then I would to devote yourself completely and prepare accordingly. I would also suggest attempting UCEED exam too. If you are able to clear it and qualify for NIFT then you would get the best fashion education in India.
