As you've noted, Lupus affects each of us differently. So, there is not way to tell you what you might expect. It is not a given that your Lupus will progress. It does not progress in everyone. If you continue to take your medications, take the proper precautions, make the appropriate lifestyle changes, eat healthy and exercise, you may be able to keep your Lupus in its present state for a very long time. You will also have to pay very close attention to your body so that if you notice new symptoms or if your current symptoms worse, you can let you doctor know and start treatment immediately! Do not over-exert yourself and do continue to take care of yourself.
Even when symptoms are minimal, I always suggest that we continue to take care of ourselves as if our symptoms were active.
If you are feeling relatively healthy now, I do not see any reason why you should not continue with school. Your goal is to maintain your current level of wellness and to make sure that you do nothing to aggravate or exacerbate your symptoms!
I wish you the best of luck!
Peace and Blessings
