SSD And the long form?

My case was up for review this year, and I ended up with the long form. This was back in February and only recent paperwork was about extra help for prescriptions. Is that good or bad and do they send a letter with regards to a decision? Also would being in college help continue the benefits if social security thought I may not be disabled, at least for now? I do want out of the system, but if I suddenly lose the benefits I would be screwed since I have no skills and that's why I'm in school.
