Fees for the candidates doing B.Tech from Guru Nanak Dev Engineering college under the SC category is around Rs. 6000 per semester which will make around Rs. 48,000 tuition fees for the whole 4 years.

The number of candidates with the domicile as Punjab under the SC category who apply in this college for B.Tech course are huge so generally getting admission under the SC category is also very difficult plus a different weightage or privilege for admission is given to the students who are coming from:

Rural background

Have the family income less than Rs. 1 lakh per year

have very good marks and rank in JEE Mains exam 

Along with this, there are lots of government policy scholarships which are mainly based on your academic performance or your family economical background. So, you can further avail these scholarships to reduce the economic burden on your family. I am not sure about the fees policy schemes as there have been a few changes made recently and you might need to give an entrance fees same as the general category student apart from your tuition fees but along with the scholarships your fee will be reduced in the same way to Rs. 6-7 K from the next semester.

Feel free to ask if you have any more queries. All the best!!
