How long after you pay off a delinquency and most of your credit card debt can you expect ur credit to go up?

I am a student with limited credit history. I got my score, 634, a month before I paid off a $200 delinquency and $1700 worth of credit card debt. Now I have much more available credit, and NO open delinquencies. So, how soon can I expect my credit score to go up? How far up could it probably go in the next few months? I haven't been late on a payment in years, I just had some early blunders at a young age. Thanks
