It depends on the person. Year eleven was probably somewhat hard for me but I had a few personal issues at the start of the year which put a lot of extra stress on me. I worked my ass off in year 11 to block out these problems and found that I was putting everything into school. By the time Year 12 came around and the other problems weren't as big I realised that VCE wasn't the be all, end all. At the start of Year 12, I needed 96 to get into the course I wanted to do. I could have achieved it but I decided I didn't want to do what I did in Year 11 to get it. I'm not naturally a genius and I would have had to sacrifice so much to get that score and I wasn't prepared to do it. I changed my mind completely on what I wanted to do and only needed 76 to get into the relevant course. I was so much more relaxed in Year 12 than I was in Year 11 because the pressure was off. I still studied and did more work than the average student but I didn't sacrifice my job or my weekends.
I guess what I'm trying to say is, Year 11 and Year 12 can be as hard or as easy as you want it to be. You are obviously somewhat committed to achieving a good score because you're on a VCE forum in the middle of January. You put the work in and you'll get good results. Yes, there are more subjects in Year 11 than Year 12, but the Unit 1 & 2 results don't matter. It will significantly assist you to understand what's going on, and if you put effort in Year 11, you won't notice the extra workload in Year 12 but in reality you just need to pass.
The only way I think people struggle in Year 11 is if you had a 'fuck school' approach in Year 10 and then in Year 11 decided it was time to care about it. Those are the people who struggle in Year 11 because they have never opened a text book outside of school walls before!
I've rambled a lot here! Sorry!
My advice is to find a balance between school, work and your social life. Make sure you don't lose your friends within school and those who aren't because you need people around you when things don't go right. No point getting 99.95 if you have no friends to celebrate it with!
Good luck
