Dot Point is good for a full revision regarding on all the syllabus
Remember HSC exam cannot give you questions out of the syllabus
But they can give you questions that have HIGH DIFFICULTY based on the current syllabus
Hence its important to be familiar with the exam-style questions - checkpoints as well
So my advice is: Get them both, and spend appropriate time on them
(Dont do all the questions on DP coz thats silly but do enough
Do lots of questions from CP coz thats what the stuff you'll be gettign in your exams)
Hope that helps
