Back in high school, I did a dump of a job in performance. My worst was senior year in which my grades were filled with D's, C's, and nearly and F at one point. I also did nothing back in high school, I wasn't very involved because I didn't carry a leadership-type personality. As for my classes, they were all regular; no AP's or Honors. All of this was a result of me not trying hard enough; I didn't try at all. I was extremely disappointed with myself. I hated this.
Currently, I attend one of the community colleges that work closely with UC's and CS's. My purpose here is to reinvent myself and although it may seem like a stretch, I'd like to transfer to Berkeley. I'm doing quite a fine job at picking myself up in a CC. I'm involved in Math programs, accelerated English (applying for Honors program soon if I keep up the good performance), and I'm putting forth more effort than ever. This should be enough proof to show that I'm capable of accelerating.
Obviously, getting good grades isn't good enough for an ivy league-- or at least that's what I think. I want to stand out, but I don't know how or what to do. I want to make myself a potential Berkeley student, and please don't mistake that statement as me wanting to over-perform. I just want to be good enough. So my question is: What would make me Berkeley qualified as a CC student?
It definitely isn’t a stretch! I’m in a similar boat. I’ve used my CC to become the student/person I really am and want to be and so far, it’s working great! 
Most of the admission decision is academic - this includes your GPA (average transfer GPA for Cal is 3.77, too bad there isn’t more info for specific majors) and stuff that shows academic rigor (you are already on the right path here! Honors program would also help if you get it). Cover the basics - major requirements and IGETC can go a long way!
There is also emphasis placed on extracurricular activities - they want to see the type of stuff we didn’t do in high school - leadership, responsibility, and the like. Get involved in clubs (especially if it’s similar to your major!) and become a board member, too. You can also be a part of the student government, and look for volunteer/intern opportunities that you can dedicate time to (also related to your major or interests). Try to think about what you want out of your education and your future, and start connecting your interests and activities.
Something that can help you stand out is undergrad research - there are a few conferences that are specifically for CC students, so look into them or ask a counselor. Attending one is good, but presenting is better - and UC schools are research schools! Even if it isn’t related to your major, it shows that you applied and were selected, and that you are getting prepared for a UC.
Good luck
