Your bank, First Bank, charges you $1.50 every time you use an ATM that is not owned by them. Unfortunately, there is no First Bank ATM near your school. There is a Second Bank ATM in the Student Center, which you use several times a week to withdraw $10 at a time for lunch, video games, etc. What is the best piece of advice regarding these transactions

Every time you are withdrawing $10 from the Second Bank ATM you are paying 15% interest (or bank expenses). That is a lot of money, so you should try to avoid doing it. You should look for a First Bank ATM that is close to your home and withdraw the money before going to school. Or if you can't find an ATM from your bank you might even have to change your bank.

If you can't change your bank for whatever reason and you really need to withdraw money from Second Bank ATM my advice would be to try to withdraw larger sums so you only do it once a week or once every two weeks. Since the $1.50 per operation is a fixed amount, if you withdraw $50, you are only paying 3% interest.
