i've always wanted to make games but did not start actively learning programming by myself until 1st year of university.

i kept going throughout university learning new languages, showing off things i had made, while neglecting my major in Biology.

Anyways, i've ended up with an Economics degree, with a portfolio of SaaS and web apps i had created so i could eat during my final year.

So far, I'm getting a few interviews here and there in web programming positions. When I get a logic pretest, I fail miserably. or job requires comp sci degree.

I mean I can easily design and code an entire app which I emphasize through my portfolio.... but i dont know why I am so slow at logic puzzles on prescreening interview...

So what should I do now ?

get certificates in languages ? go back to school and learn CS ?

is it too late to get into windows programming jobs than web programming ?
