Hi tapanjit
As you have secured 49 Marks in Cee 2019 under ST category which not pretty good enough .
So, your chances to get admission in AEC is very low.
Since, you may be knowing that AEC is the one of the most demanded college under Assam CEE.
So, everyone tries to make it to AEC, so it's a bit difficult if you don't score better.

However, for further information you can refer to the following link
