Sir, firstly congratualations to your whole family for your ward's excellent performance in both the forats of the paper.

Sir, Though without the information of Home state and category of your ward, it has become bit difficult for me to answer.

Though, I would consider him a GEN and non-EWS aspirant.

With these ranks

1. He will surely get CSE in all the new IIT's

2. He will surely get CSE in all the NIT's except NIT Warangal and NIT trichy.

3. He ahs a huge chances of getting CSE/IT in IIIT Hyderabad

4. He has almost no chance in getting a seat at old IIT.

So, I would recommend him to go for 

1. IIIT Hyderabad  IT/CSE

2. MNNIT CSE

3. NIT Suratkhal CSE

Thank You
