I've been considering for a while dropping one VCE subject next year so that I can dedicate more time to my other four subjects. I did History Revolutions this year as a Year 11, and next year I'm doing English, Further Maths, Psychology, Legal Studies and Viscom. I don't know what I want to do at uni yet so I would like a decent ATAR so my options are open, and I'm not sure if dropping a subject will disadvantage me.
What are the pros/cons of only having 5 VCE subjects?
If I should drop one, which one would you recommend and why?
Thank you so much for any help in advance! And congratulations to all Year 12s today who received an ATAR 
I personally will be doing 6 subjects next year, but I see where you are coming from. The problem with doing only 5 year 12 subjects is that you are going to have one subject less in your aggregate score, and at the start of Year 12 you have no idea which subject is going to be your worst. Once you have 5 subjects, you do still have time to devote to your other subjects. On the other hand, sometimes the extra time can help.
If you do decide to drop one subject, it is totally up to you which one you drop, but on the whole, play to your strengths. Of the subjects that you have listed, VisComm is likely to be both very time-consuming and it is often harder to score high in, as it requires a huge amount of work. That would just be my suggestion, but yet again, play to your strengths. Good luck!
