Affiliate Marketing Secrets

Now a good paycheque is very important to me. I have a Bachelors In Electrical engineering. I love technology and i’m also good at managing people.
I know about the wide network an Mba allows you to develop and the never ending opportunities in a variety of sectors for an Mba graduate. Should i choose this over the niche field of electronics where opportunities are few but the pay cheque would be on par with an Mba grad?
I have loved electronics and has been a childhood dream to work in a lab where world changing work goes on.
I sd keep in mind even the tuition fee for both. An Mba in IIM wd cost me around 13lac while in IIT/IISC id be paying peanuts.
I want to write either GATE or CAT and have given myself till end of nov to decide which. I don’t mind the hard work needed to be put for either.
Any and all kind of advice is welcome and highly valued! Thanks!
(I’m working now in the software field if thats anything)
