I’d caution against choosing “easy” subjects for points because it’s not quite that straightforward.
Some of the “points subjects” have a lot of rote learning (or did back in my day and maybe that’s changed) and I struggled to just learn and regurgitate facts. I performed far better on subjects that required a bit more analysis or a creative approach.
Sometimes the honours courses are more interesting and engaging than the lower levels - maths definitely is, though it had been dumbed down a bit when I was doing it and some of the connections between different aspects were lost. But I was a student who needs to grasp the big picture and I would have struggled to get to grips with lower maths even if it’s ostensibly easier.
Art is consuming if you work on building a portfolio but it’s very manageable otherwise and can be a great change of pace from the academics.
There’s a lot of exam craft that wasn’t taught in my school anyway, and the best advice I’d have for anyone is learn how the papers are marked and give the examiner what they are looking for. You need to hone exam craft over the next two years.
Quick examples are if you have 30 mins to write an essay, and it’s optimally marked based on 6 paragraphs of 10 facts with an intro and conclusion then write every essay either
• in 30 mins aiming to get better marks each time, or
• in the 6 paragraph format aiming to get quicker each time.
Or in maths learn to write the solution in a way that gets every possible mark (by showing each step clearly) rather than doing it in your head, and making one tiny mistake and losing all the marks.
Try and figure out with her what sort of learner she is. Some people do better with overlapping subjects like maths/applied maths/physics and some benefit from a wider range.
And not to be negative, but she’s young and they do change their minds, so allow for that too.
A lot of universities require a modern language.
