I have been a PC hardware tech since '95 and I can attest that not only can trained monkeys do the job, but some untrained monkeys as well make the cut.
For real though, real world experience is CRITICAL to making real dough long term. Your first problem is that you have no idea which courses to take because you have never likely done anything related to any of these courses. If you have never built a PC, written ANY code, programmed ANY router, have any idea what an IP address really is, know what DNS or DHCP are, then you should consider another field of industry. Sorry.
