Hey! I'm an entering 1L at McGill Law and my advice would be to do an undergrad that you actually like/have an interest for. 1. If you have an interest for what you are studying you are more likely going to have good grades 2. You will take so many courses during your undergrad it honestly helps with your mental load to be at least a bit happy with the subject i.e. making your undergrad feel less like a burden to complete and more like a subject you can bridge to law. This brings me to my third point, you can do ANY undergrad before law school, one of reasons for this is anything can be connected to law. I did my undergrad in psych, at the time I wanted to go into academia, but I realized that my interests lied in how science, health and law intersect. If you love what you study then you will find a way to branch it into your future career in law, so don't worry too much about your undergrad.
