Hi there,
Your UPSEE rank would be around 24k-26k for a rough estimate. So the most probable colleges where you could get CS or IT are
1) Babu Banarsi Das Institue Of Technology, Lucknow

2-Sri Ram Murti, Lucknow

3-RD engineering college, Ghaziabad

4-ABES, Ghaziabad

5– United college of engineering and technology, Greater Noida.

Try for these as they are most probable for you.
Thank You.
