Hello
If anyone can guide about the criteria upon which uol accept applicant.
When to apply
What to expect

Which law schools? You should list your interested law schools either on your post topic or on your thread.

Normally, most of law schools would open an application portal on January while some may open an application earlier. It could be on September. 

Depending on the admission system, it can be either a rolling admission cycle or first-come first-serve cycle as well.  

You could expect the result within 6-8 weeks in general. 

Hope this helps.
