I think that this is wise! Finances are indeed a challenge for most DVM students. My daughter has said that she is pretty sure that most of the students that she knows in the same program are taking on too much debt, but that no one wants to talk about it.
It did occur to me that taking some community college classes now could be a very economical option. This will be fine as long as you take the classes quite seriously and do well in them. I would also be careful regarding what the prerequisites are for any specific course that you are planning to take. Anything that is related to veterinary work and that you can get an A in will be helpful. I would try not to pile up too many B’s or particularly C’s, but a few B’s are okay (my daughter for example had a B- in organic chemistry and this did not seem to hurt her acceptances at all – she did say that is was the most difficult B- that she had ever had through getting her bachelor’s).
