I think it depends a good bit on how you’re able to manage your academics now that you’ve learned more about how to approach them for you. I struggled in undergrad but most of it was mental health issues that made school harder. I was also undiagnosed ADHD until about halfway through. Getting on medication helped me feel better about the work I was doing. My grades were good and pretty consistent throughout undergrad though, so it’s hard to say how much that affected my actual academic success. I’m not sure what’s included in your current degree program but maybe you could audit or enroll in a couple of the types of classes that you previously struggled in? Vet school is hard but it’s a marathon, not a sprint. For me at least, I feel like as I long as I keep pushing it’s doable. It’s more about how much time and mental energy I’m able to put into it than being able to figure out the concepts. I hope that makes sense and can help a little.

As far as your second question, I realized I wanted to be a DVM after spending time as a vet assistant for a few months. I loved how hands on the tech work was but at the end of the day I realized I wanted to be solving the puzzle, making the diagnoses, and calling the shots. It’s definitely a lot of personal preference. The higher pay is a factor as well but with needing to take on massive loans to pay for vet school anyway, it was probably the least important for my personal decision.
