Greetings!

Well there are a few key points that you should remember while doing COMEDK or any other choice filling.

1> First and fore most is have complete knowledge of your choice, if you are filling some college or a particular course then you MUST have some idea about what it is

2> Fill as many choices as you can, there simply is no harm in filling choices which you think are not so desirable, I mean you can just drop that seat if you don't want that in the end, but in counselling you should be filling maximum choices

3> Third and perhaps the MOST IMPORTANT one- FILL IT STRICTLY IN PRIORITY ORDER, many students every year make this mistake, that they fill a less desirable choice over more desirable one, just because they think they are not going to get that one any way, and then they end up getting that branch...

Now to check in which colleges you can get into at your rank and to have more insides on it you can use the following tool
