Congratulations on having a head start on mustachianism and retirement investing at 19. You will be fine almost whatever you do. Having some paid work while a student looks good to any potential employer, but not so much that your grades go below the usual employability levels for the sort of jobs you will want.
Those rates of interest on potential student loans are higher than you could expect to earn from investing, so arithmetically speaking you should concentrate on putting your earnings towards not taking out student loans rather than putting more into a retirement fund. I would suggest leaving that fund as it is for the time being. Or perhaps put any future gifts into it to round it up to a easy to remember number you can look back on in 20 years? It's a nice start for your future self whatever you do.
I'm assuming here of course that any earnings while you are a full time student will be low enough that you are not paying much or any tax on them - if you are going to be paying tax then the calculation might change in favour of some more tax-free investing.
You probably need a limited amount of savings/emergency fund while you are a student, on the grounds that you won't have financial responsibilities to anyone else or ongoing and relatively immutable expenses such as a mortgage and that you have decent health insurance. That means your current level of savings looks OK to me. You might want to revisit that going into your final student year because at the end of it things like interview expenses and moving expenses, rental deposits and car purchases could start to kick in before wages start being paid.
I personally did not do well my first semester, 18 credits was a bit much for someone who is still learning study skills, ended up with a 2.2 gpa. I am retaking 2 courses with grade replacement which will bring it back up. I have accepted that I will have to attend a local community college this summer to catch up and would like to pay for my mistake 1st semester, my parents were so understanding. This semester having only 12 credits a job part time ~20 hrs. is going to be helpful in scheduling myself out.
Thank you, yes it would be nice to keep track of where things came from. I have a detailed binder where I note gift amounts and the giver as well as how many stocks the gift purchased. It should be nice when I am looking back to say that $60 the _______ 's gave me or that $100 my uncle gave me is now worth, (insert exorbitant growth when I am 40/50).
I am more concerned now about saving up to prevent more student debt thank you for emphasizing the reasons that is more important! Even more so since I am losing a scholarship next year.
Taxes will most likely be in my favor as you stated, or at least the amount of income so small that they wouldn't be too bad.
Ok is not Ideal I understand, with your insight I am going to change my plan to only save to pay off debt and an emergency fund maybe around 2K just to be safe (by the end of this year) the rest will go towards saving for next years tuition. Thank you very much for your response, it means a lot to have some insight, especially being so young at this.
