Yeah that's true.
To be honest after slacking off in legal for the year and only averaging A's in both GA and putting in my aims for my subjects next year via atarcalc (year 11 student here), I found that if I studied like crazy for legal, to my ability I could see myself getting 37 raw, which would contribute 3.7 to my ATAR, whereas if I didn't study I'd get 3.0. Needless to say, I've studied as best I can to redeem my poor SAC marks and am hoping for the best - I'm strangely relaxed about the exam, which at the same time worries me.
Just looked at my Legal Notes and what do you know - completely missed that they provided practice exam booklets! Wish the teacher had informed us, ugh.
