Working full time along with uni

Hey guys, I took admission in Iqra uni and my classes will start from next Monday. I work full time at night from 9 pm to 6 am. Is it possible to continue my studies with the job and if that is possible would I be able to get 7 hours sleep?

Also plz share with me when does uni starts and when it usually ends and how strict is attendance in Iqra uni?
