Dear Ahtesham Ul Haq,

Online survey business is doing pretty good these days and it is here to stay, you should use your time intelligently and complete your B.tech in which you can take admission after 12th. You can take a short course in online marketing.

This will surely help you....wishing you all the best

Yes you can take but you might have to apply for it separately

Dear Mohammed

It's fine to start that business but in order to have prior experience you need to complete your b.tech in instrumentation engineering and also if you do mba in marketing. Then you'll rock in your business.

All the best.
