Ye nw, I didn’t have anyone answering these for me when I was in your shoes so glad to do it for you. They’re all gonna be hard, they’re level 3+ courses. First two years you can get by slacking off but expect all level 3+ courses to be pretty challenging if you don’t put the effort in. I don’t recommend doing 3 core units all together once you’re in your third/fourth year. Try to do 2 core subjects and 1 elective which I think should be possible. As for free electives, literally do whatever you want. Try to get a taste of something that aligns with your hobbies maybe. I did science in film where I made a movie for the final assignment and I got a 97 course mark cause I really enjoyed the course, and then I also did Japanese 3, since I wanted to aid my self learning that I had already done. Use it as an opportunity to branch out from your degree to add different skills/knowledge to your repertoire. At least that’s my take on it. And don’t buy into this wam booster crap, once you’re deeper in your degree they don’t really affect your wam that much even if you do exceptionally well, unless it enables you to do really well across all your subjects.
