U said u r a computer science student  so why do u care about class courses? believe me u will get almost nothing from the school as a cs student just the degree that will help u an employee of banks or some local shit IT companies that will pay  u 10k or something. Why bother restarting university after two years?  Instead of starting over, just add the missing courses to your current program.  Focus on self-learning and developing practical, marketable skills.  That's the real key to earning good money or get the necessary skills u need.  Don't waste extra years on school!
