This is what worked for me. So take this all in the context of it being one person’s experience.
1. I think that if you specifically want a good number of hours plus money, then working at a vet hospital as a tech/assistant is a good idea. You could do something like 20 hours a week while you’re still in school, and then up that when your graduate. It’s not enough to impact your academic performance (obviously your experience may be different though) but enough to make good money and gain a lot of hours. Especially if you’re worried about your GPA holding you back. A lot of schools are moving to a holistic admissions process, so having lots of valuable experience can help to make up for a lower GPA, especially if you can’t bring it up much from several semesters of bad grades.
2. Don’t eat out much if you can help it. Buy groceries and cook. It’s much cheaper. Don’t splurge on things you don’t need. Or at least don’t do it often. You want maybe $3,000 in a savings account to keep you from worrying about any sort of finances while going through the process of paying for the GRE, applications, supplemental apps, and interview expenses. If you apply to 5 schools and get interviews at all of them, that could go up to or above $2,000. Shoot for as much in your savings as you can. I had around $4,000 and I went through most of it, but I also applied to 11 schools.
3. I think you get tons of real world experience that you have never had before. You’ve been in school for nearly 2 decades with presumably no breaks. Use this as a time to learn what life is like outside of school. You’ll grow a lot, meet new people outside of an academic setting, and hopefully gain pragmatic experience in the field of veterinary medicine. It can teach you what it’s like to really work in the field without the haze of school, and without only working in small bursts. The cons will be in the next part.
4. This entirely depends on the person and their dedication to becoming a vet. It’s one year. If that small period of time makes you think it’s not right for you, then good. It probably isn’t. If you come out of it still feeling as strongly as you ever have, then it’s probably right for you. It’s a huge decision to go to vet school. Don’t take it lightly, and don’t fight it too hard if you feel like the gap year is changing your interests. This is the rest of your life you’re working towards. Don’t chase something you don’t really want to be doing. So actually that’s not a con. That’s more of a pro if anything.
5. I loved my gap year. I worked a lot, saved money for rent payments and furniture for my apartment at school, and grew a lot as a person. It really did so much for me. I would recommend to anyone who isn’t sure about going to another 4 years of school right after college to take a gap year. It’s the best way, to me at least, to figure out what you’re doing with your life and to get all of your affairs in order to handle what’s going to be a very tough next four years.
