These are designed for in demand gigs that lead DIRECTLY to employment. You only do 3-5 bullshyt gen ed's classes and then you're taking relevant courses with the AS degree's.
If you can get a computer science, electrical engineering, medical doctor, biotech degree...DO IT. Those field will be in demand and offer competitive pay for the foreseeable future. The key is to intern and gain experience BEFORE you graduate. Get a tutor, self study calculus and physics and you will be fine. On the entry level side there are the Comptia certifications: A+, Network+ and Security+. Cicso has the CCNA. Microsoft has the MSCE. Self study and acquire the certifications.
