I assume you were put on academic probation before you were dismissed. That should have been a wake up call. To be clear, the college has said you can return after one semester? What are the conditions?
Read this post, which offers great advice on how to succeed in college: http://talk.collegeconfidential.com/college-life/1920853-college-is-a-step-up-from-hs-16-tips-on-doing-well-in-college.html#latest
I’m guessing in three semesters, you had twelve classes. You got unacceptable grades in nearly half of those classes, and you’ll probably have to make up the failed courses. Contact the academic advising center at your university and visit the community college to ensure that any course you take at CC will transfer over.
Community college IS college. You will be expected to attend class, do the work, and study. It’s called earning a degree for a reason. You have to work at it. It sounds as though you thought you didn’t need to do the work to get the grades, and now you’ve discovered the truth. Only you can decide what you want your future to be like. Partying and video games won’t land you a decent job, so make a commitment to follow the advice in the linked post.
