Glad to hear you will consider DNA testing if your studies come to a halt.
Let me speak frankly (I can't help it; it's the Alexander in me, sorry.).
I and many other testers have first had the same thought.Over time I and many others learned that: 1. Whatever you learn in your studies, it will never be everything you want to know about your line. For example, let's say you trace yourself back to your "immigrant" which is relatively easy.Then you will want who the ancestor of your "immigrant" were.Pre-immigration records are much more scarce.So then you decide to test. 2. No matter how "factual" your paper trail is, you still cannot be certain of it until you test your DNA.I and 4 others were "sure" we had traced ourselves to an immigrant but we did not DNA match others who felt they were descended from him.Selecting other testers we were able to pinpoint the generation which had an error in it on our part. Furthermore, early parent deaths and subsquent adoptions were quite common. 3. DNA testing always yields knowledge you did not have before, even if it confirms your paper trail. 4. It's easy and it's fun.
So my friendly advice is I predict you will eventually test your DNA.And the sooner you do it the sooner you gain that knowledge and can thus take advantage of it in your efforts.
