Currently, I'm doing 5 VCE subjects and I'm in year 12. One of my biggest regret was not undertaking Biology 1/2 in year 10, which I would've finished in year 11. It would've given me a head start, big or small, but regardless, I'm still aiming for a 90 atar with those 5 vce subjects of mine. I work on the weekends, around 4-6 hours per shift in the city, so a lot of juggling between work and school. I stress a lot, I cry a lot when I get my physics scores back, but I'm not giving up until I finish my exams. My teachers even predicted that I would get at least an 80 atar, so you're in a very good position with your 41 SS and 39 SS.
Furthermore, you dropped the subject that would've been your bottom 2, it won't affect you that much if you're looking at a mid to high 80s atar. Focus on your English! (Since that's where most people are struggling, including me.)
