Hi DanyDavito,
Not late: You need to do the following (assuming you already have the acceptance letter from the university)
1) Apply for the CAQ which will take approximately 4 weeks (if the application is complete). You may add a week or so for postal delays.

2) After getting the CAQ, apply for the study permit at the CHC in Accra. The posted processing time for a study permit is 3 weeks (mailed application) and 1 day (in person at Accra CHC), but if you need to do a medical, it may take more 2-4 weeks.

You need to start the process now!!
