Best wishes for your spiritual inclination,first.
Helping as a student to a student is highly great thing. Not only now, it was in 1950, my paternal uncle had a close friend, named Sundaram. One day my uncle prepared for an examination by thinking that day was chemistry examination but actually on that day it was physics. The friend came to our house in the morning to fetch him for the school but on understanding my uncle wrongly prepared. He consoled him not to worry for anything and he told all important questions which he prepared while going to the school (the school was at 2 kilometer distance and they have to walk the distance daily). With that hearing only my uncle passed the paper successfully with a good marks. This was told by him to us very often to us by remembering his friend.
Similarly my elder brother during his college second year final examination, got severe fever and by force he gone to appear for examination. I read all the lessons of important portions on the way to college and he did his examination well and passed out the paper.
So, it is good thought of helping others. You can help final year students for preparing projects etc.,
