As Year 11 subject selection dawns upon us, I have found myself reconsidering my original plan to study Revs 3/4 in Year 11. My main concern is the workload - I intend on also taking Bio 3/4 in Year 11, and as both subjects have a ridiculous amount of content, I feel like I'll be in for a rote-memorisation-fest??? I know that I have an excellent work ethic. But at the same time I would like a score of about 45 in both - is this somewhat feasible, especially if I am also trying to balance with 4 1/2s?
What is Revs in general like? How difficult is it to break a SS of 45? Is the workload very intense? Am I better off leaving Bio until Year 12, or not taking Revs at all?
Any and all opinions much appreciated 
Hey! I know this was posted aaaages ago but i just came across it and i think i'm the perfect person to answer this, so might as well!
In year 11 I did history 3/4 and bio 3/4 alongside four unit 1/2 subjects! (english, methods, media, and theatre studies).
In terms of workload, it wasn't too difficult to balance history and bio! they were both super interesting and very different from each other so studying for one was a good break from the other. Both did involve a lot of memorisation, but I was good at memorisation, so that didn't bother me. The only difficulty was time management. It was hard to balance alongside all my 1/2 subjects. I thought I would be able to handle it since theatre was a bit of a bludge, and I was repeating methods 1/2 so I already knew all of that content. But it was just really hard to have good time management with all of that going on.
I ended up with a 38 in bio and 40 for revs. I was super happy with that, but I know that I could have done so much better in both if I had only been doing three 1/2 subjects! Just having that one less subject, and therefore actual free study periods at school would have made SO much of a difference.
History is super difficult to get a 45. I think history is an absolutely great subject for anyone to undertake (I just finished my third year of my history major at uni), but to get 45+ you need to not only have an
interest in history, but be super passionate about history, willing to do extra readings, and go above and beyond what your teacher asks of you. A 45 is achievable, but you reallllyyyy need to work for it. I would say the same for bio; if you're super passionate and dedicated, a 45 is definitely within reach.
That being said, in my opinion, both of those subjects are really worthwhile doing, regardless of whatever study score you think you will get for it. Both teach you super interesting content about the world, and both help you develop really different skills. I would reaaaallllyyy advise you to choose subjects pretty much purely based on your interests and not on their potential to be ATAR boosters.
tl;dr: i think doing 3/4 history and bio is manageable and fun, as long as you're only doing three 1/2 subjects max !!!!!
