The fact remains that the ealier you start taking risk as a student, the strongeer you become to face the world after graduation, for me i will advise you should invest some percentage of the money you save.
I think this is high time for op to try something else at least trying getting a small job even though the one he would be doing when he closes from school. That would be a better alternative and it will bring more money to him.
He can apply for work and be doing that in the night after school closes to makenextra penny so that he would have some casho to save and prepare for the time when there will be no fund at all. Saving is a good and those who had mastered the act of saving are in deed benefiting from it which is a very good thing to do now that he's he school with no one ready to help at the moment.
I will support your thinking, he should find a job that will be better than thinking about using part of his savings to invest. For students, the investment will put them under pressure, thereby affecting the learning process. They should only invest when they have enough savings as well as when the investment must be in a comfortable mood, without too much pressure.
Part-time work is something that I think any student should have, it helps them both have more income to cover their studies and have a better life experience. When they work as hired laborers, they will feel how difficult it is to earn money, from which they will try harder in their studies.
