Fashion Design

The best guide books for NIFT entrance exam are these:
1. NIFT Entrance Exam Guide by Surendra
2. NIFT Exam Guide by Verma
3. Prashant Kumars NIFT Entrance Examination Preparation Guide
You can access all these by joining a good coaching institute. I think ICAD India is one of the best coaching centres for NIFT entrance examination preparation. They show good results.
Other than the ones mentioned above, one could also try these following books:
1. Bright Careers Guide NIFT Entrance Exams
2. NIFT/NID Exam Guide by Datason RP
3. Concepts of Pattern Grading
Practice is the key to success and one will do better if he/she joins a coaching centre.

That depends on your interest. There is no specific course that we can tell you to pursue without knowing your interests.

You can still prepare for the Masters in fashion designing entrance exam.
