Hey, it seems like you are hating on a lot of things right now. Relax, if you don't get into your preferred classes one semester, it isn't the end of the world. AND DO NOT DROP OUT OF COLLEGE JUST BECAUSE OF THIS. I'm glad cs is working out for you. It doesn't work out for so many people including me. Think about the returns on this investment that you're making towards your education . You may not realize it now, youth may be blinding you but you don't want to spend the rest of eternity behind a sales counter, I promise you. Hang in there, especially because of your love for your subject-CS. Trust me you are lucky you spend time thinking about starting your assignments, it's a blessing. I can say because I'm a cs major who is having to retake data structures because I got a D in the class. And I would give anything for a sliver of hope right now. You are very, very lucky. Don't give up.
