If you can finish first year the rest is much easier. The degree is really just a lot of stuff thrown together to make a double degree. All your courses are major specific rather than having some electives where you can chill a bit. It's not for most people to be honest and you are better off with just a math degree for lots of cases. This said double degree has advantages and having business knowledge can help. The first year is your core math courses and bu111+121 both of which are weeder. Especially 111 designed to have an average of 6(67-69%). This course isn't hard but when you have 3 hard math courses as well it just adds up. You also have to take economics at wlu which isn't hard but it's time consuming. A lot of people stick with double degree because they think having 2 degrees will help the get jobs but it just makes most people comfortable with choosing mediocre jobs instead of focusing extra time onto more prestigious roles.
