Missed school days, now suspended license?

In the state of Florida students aren't allowed to miss more than 15 consecutive school days in a 90 day period. Well I did that and I got a letter in the mail about an Intent to Suspend my license unless I go to school for 30 consecutive days with no absences, and receive a reinstatement form from my schools assistant principle saying that I did so. Well here's the bad part, the letter then says towards the end that I must meet this requirement within 20 days! How is that even possible?! But wait, it gets worse! It's near the end of the school year and there is not even 30 days left to go, and I really need to keep my license. I've been told that I can make them up over summer school but I really need to keep my license in order to even get to summer school and my job. So my question is, does the FLDMV check to see if you've been going to school and that your making up those 30 days? Or do they take your license after 20 days no matter what?
