Purdue readmission

My cousin is a sophomore in CS who is a brilliant student who has a percentile of 90+ in all exams but recently he was sick and couldn’t write the final exams well and failed in the exams and was dropped out of the college.
What can he do next to continue in a good college?
Is there a chance to get admission in Purdue again?
if yes, what is the procedure?
his idea is to join a community college for 6 months and then again join Purdue, what do u think of this?

I think the fact situation you describe doesn’t ring true. But in any case Purdue itself is the only reliable source for information about readmission.

The fact is that my cousin’s professor “eugene spafford” gave some ridiculous grades to him and most of his friends
