Product designing has gained a lot of popularity in these growing years and it has a great scope if you gain excellence in it.
For getting into product designing you should go for a degree course in designing. Firstly, you should complete your 12th (from any stream with minimum of 50%) and then apply for designing entrance examinations for your chosen institute. NID is a good option for product designing.
