hello karuna!!
with 87.8 percentile in jee mains 2019 and with sc category rank 6015,i am sorry to inform you that you wont be getting a seat in ECE OR EEE branch in NIT HARIMPUR IN OTHER STATE QUOTA.

HOWEVER WITH HOME STATE quota you may have fair chance to get a seat in NIT HARIMPUR.

Also there are many others colleges in which you can get ECE and EEE branches.

I m providing you a link for  knowing colleges in which you can get a seat for your rank  in JEE MAINS  and category,please see the following link :
