The Mathematics department of NIT Jalandhar is newly established and so not at par with the M.Tech. department. The faculty is not that experienced either and you will find assistant teachers more. Most of the NITs don't have faculties of varied expertise for the MSc program. Moreover, placements are also just average. Most of the students apply for teaching jobs or Ph.D. So opt MSc in Mathematics only if it is your last choice. But if you have already joined it or are adamant about joining it then these tips will help you make the most of the course:
Keep in touch with the Mathematics fraternity around the world
Attend Mathematics seminars and conferences which will give you a better understanding of the subject and its applications.
Initiate things on your own during college seminars, departmental events, or technical fests.
Lastly, focus on your academics
You can make the most out of the resources of this department even if it is lacking in many aspects.
