Electives vs full course load
So, I'm entering Level 2 computer science and I have 6 free units to spend. I am using 3 of them to take a 3rd year comp sci course, but my remaining free units are kind of causing me a problem...
Any electives that I'm eligible for and even remotely interested in are either full or conflict with my mandatory courses. So my question...
Is it necessary for me to take a course to fill in those last 3 units? Like, if I were just to take the 9 courses instead of 10, will that cause me any problems? I'm not sure if this is a stupid question or not, but I've had a lot of trouble finding an answer.
Any help would be greatly appreciated!
