I passed my 12th in 2015. Will it be a good idea to opt for engineering? Will it give good results?

Yes, you can pursue engineering. It has a good scope.

Hello Mihir, Yes, you can opt for engineering. All that matters is your skill set. At the time of placement, you might be asked about the reason for the year gap. Just be honest and tell the truth. If you've the knowledge and skill set desired by the company, you will have a great career ahead.
