TRANSCRIPT
Use the following list to tick what skills and knowledge you need to be competent in for the upcoming exam:
If you are working only to pass Mathematics only focus on Level 1 and 2.
If you are working to get more than 50% in the exam you will have to be competent with Level 1 and 2 FIRST,
then only focus on level 3.
Do not fool yourself: if you are not competent in level 1 and 2, working on level 3 is futile!
