1. Yes, it is. Anyone who is sitting in a 4U classroom for a whole year will eventually be able to do it with practice and understanding. Stop putting the course on a pedestal. Why wouldn't any remotely good at maths not want to do it? I'm going to tell you a little background of myself; a few years ago when I was in Year 9 I was failing absolutely everything in Maths and rather badly too, and I only had like 2 good tests for the whole year, not because I found it "hard" but because I was barely listening in class, not doing any revision, didn't make any effort to ask questions for things I found difficult, or else I am sure I would have done much better. I was so bad, in Year 10 I was reccomended no maths, but then it suddenly clicked to me. I had to stop being lazy! If I wanted to get better, I needed to find that fire and that motivation and that hunger to do well. I started setting up myself a study timetable and I told my parents to block facebook, youtube, or any other non-educational websites, and I even started seeing a tutor, and with those small steps, I started getting better; my results were improving, and as I started making studying my biggest habit, and my results skyrocketed by so much, that at the end of the year, I ended up with an A on my report. That exact time a year ago, I was getting an D. And then obviously for Yr 11 I picked 3 units of Maths, and then 4 units in Year 12. Now if someone had told me 3 years ago I would be doing 4 units of Maths in Year 12 and finding it simple, I would have told them that they're living on some other planet. So ANYONE can do it;doesn't matter how clever you are; saying it is hard and all of that crap, that's just being lazy, like it or not.
2. No, but that's pretty much what you need to start off with.
