You are correct.
10 mark question- last question
you choose to do part a or b
usually one questions reflects unit 3 coursework and the other, unit 4.
Guys, just don't become complacent with smaller mark questions. Don't go overtime (self-imposed timelimit) starting the last question and working backwards and then end up rushing the smaller mark questions, not giving sufficient detail, not reading the question correctly/fully in your rushness.
Just remember that it is easier to get full marks on smaller mark questions than it is for a 10 mark or 8 mark questions because there is more information required to obtain those marks, thus you may write a long answer for last question thinking you will get full marks and you might only get 7 marks depending on the QUALITY of your answer, not just the quantity, and in this process you may sacrifice the time on easier questions which you end up losing marks on.
I only suggest this approach for people who are known to finish with time to spare, because if you are less likely to rush through the smalller mark questions. Also a tip which you may or may not know. If you get to the 10 mark question with 5 minutes left, DO DOT POINTS!!!
You can't do this for all questions, but just if you are running out of time you can get assessed on your dot points.
I knwo a girl who did dot points for the last 3 questions and got 42 in legal.
