Hello Peesa,
Seats in IIST are allotted strictly as per your rank. If they have your desired Specialisation at the time of Admission then you must give your choice for this. But possibly it could be optional subject later on then you have to choose main branch first.

If your mains rank is above 70000 (general), you can try if not, you need to work really hard. I have dropped one year but that year was like a nightmare as I studied around 12 hours a day. So, I would suggest you to think once again finally.
All the best.

This is pretty simple. Just refer for Arihant's NIFT book and some sample papers from google for NIFT exam that will be sufficient. Also, be in touch of day to day news regarding fashion industry.

If you studied 12th then you can definitely appear for JEE Mains. If you joined Diploma after 10th, then you can't apply for JEE Mains.
