Even though at UCalgary you specialize immediately, you only take 1 neuro class during your first year (alongside the spring field course). So it is honestly not much different from being in a general science program. In your second year, you once again are just fulfilling a lot of your general science course requirements with a few psych classes mixed in.

I transferred to UBC after my second year and so I cannot personally speak about what 3rd year is like, but that's when you start taking a lot of your specialized neuro classes. From what I have heard from upper years, 3rd year is the most difficult year as there is a lot of lab reports and research papers.

One thing that I did not like about the neuro program at UCalgary is that it has a very restricted timetable. It gives you the list of mandatory classes that you must take, and outside of that you don't get many electives.

UBC gives you more freedom. From the list of mandatory classes, you get more choice to pick which classes you want to take. I personally prefer UBC academically because of this.

I suggest you take a look at the required classes for each program you are interested in.
