Hello AKASH A S 

I don't think You will get a seat in PES University. You can go for second round of counselling and you might get Biotechnology or Civil Engineering if your luck is extremely well. Getting CSE or Electronics branch is highly impossible. This is because PESSAT is for admission in a single college and they have limited seats. Plus it is one of the premiere institute, so people are not willing to give up their seats. Anyways, hope for the best.

All the best!
