A character certificate and a college leaving certificate are two distinct things. They might be included in the same piece of paper but they serve different purposes.

A Character certificate states out your moral conduct or behavior (good or bad) during the time you were in college.

While a college leaving certificate or migration certificate helps you to get admission into universities other than your parent university for further studies.

The provisional certificate however is a provisional degree which you can use instead till the university issues the final or original degree to you, which normally takes up to 5–6 months or a year in some universities.
