I'm currently in college taking general programming and I'm about 1.5years into that and I need to do a co-op to graduate, but despite being in college and regularly doing programming outside of school as a hobby it feels like it's just a hobby I don't feel like I actually have what it takes to do this as a career.

The reason why I feel like this and I'll use my hobby as a example I've been learning C++ for a little over a year now because I became really interested in graphics programming and I've learned a lot I really pushed myself to stick to it and to try and learn as much as I could, but my knowledge is just terrible like sure I can somewhat comfortably write simple C++ programs and navigate through the language and my ide and all that, but if I was asked basic C++ questions like to write a loop or like a templated function I'd probably blank which probably isn't good.

I understand that a co-op is there to learn and gain experience so I'd imagine companies probably aren't expecting you to be cracked out, but yeah I don't know.
