Dear Moumita, 

The result of AIBE 13 is expected any day now. As per the previous year, it was scheduled for the last week of December 2018. You can keep a track of the same at the URL given below. It will be updated with the link to check the result as soon as it is out. 

Coming to whether you can visit courts without Certificate of Practice (COP), yes you definitely can. You can visit courts, witness their functioning and also attend most proceedings (if not generally, with permission). You do not need COP for visiting and being a witness to the functioning. However, if you plan to practice, then you do require COP.

Hope that answers.

All the best.
