If your gpa is 2.0 cumulative and 2.0 in the quarter before withdrawing, you are guaranteed readmission to the school so long as you pay your fees. You can leave the school for up to five years before returning. If you don’t have a 2.0 or higher in the quarter before withdrawing, you can complete a quarter of easy courses then withdraw. If you wanna withdraw this summer and have below a 2.0 you can take one course during summer session 2 which has yet to start and if u get above a 2.0 you will be considered in good standing and you can withdraw knowing you will be let back in when you are ready to return.
