Same Deadlines of 3 different courses

I Accidently choosed 3 courses at the same time so now all 3 courses have the same deadline .please tell me what should i do to get different deadlines of the 3 courses

It’s not a big problem. Just follow any one course and leave the other two courses. After completing the first course, go to the 2nd course and reset the deadline as shown here. Do the same for third, after the completion of 2nd course.

Best,
Saif.

Thanks alot for helping me
