I'm in year 11, and thinking of only keeping ten units for year 12.
Your views pls? Experiences, a friend of a friend, etc?
I'm on 10 units atm.
Used to think it was risky as well - like most people wanting to do only 10, I had the thoughts that physics was my worst, easily wasn't going to be counted. So I dropped it - never have regretted it.
That's because I absolutely hated it - not because I was doing badly in it, but because I genuinely had no interest and I was
exponentially better in my other subjects (by at least 40%).
Before you consider dropping, think it over seriously for at least 2 weeks. I stuck with physics from the end of prelim year til the middle of this year. I was 100% sure.
Otherwise, I don't see why not - I was excellent at my other subjects, and if physics for me was such a huge outlier, it was the most strategically advantageous thing to do.
EDIT: reading the posts above mine, my experience with the stress is different, it actually takes it off for me, because physics is 1 less subject I'd have to be cramming for. I was absolutely hopeless at it anyway.
