Hello Aspirant,

The rank is based on 50% pcm and 50% kcet marks.

So pcm marks 284 is percentage ((284/300)/2)*100=47.33

So Kcet marks 80 percentage ((80/180)/2)*100=22.22

Total percentage is total=47.33+22.22=69.55

You have nearly 70% percentage for you.

So you may expect a rank is between 8,000 to 15,000.

I hope this information will help you.

THANK YOU.
