Fix Your areas of weakness
Constantly review your work. Develop a habit to check every problem for mistakes. Make sure you’ve added up correctly by double-checking with your calculator. Work out difficult problems in two different ways and see if you get the same answer.
Get in the habit of finding your mistakes and fixing them.
Another great tool to use to fix your weaknesses is a list of mistakes or errors. Here’s a few examples of errors/mistakes:
- You know you always forget to write the units at the end of a question
- You forget to convert different units in one problem to the same unit (you can’t use cm, m and mm in one problem, you must convert them all to one, for instance convert all to cm)
- You get so busy with solving you forget that the question asked the coordinate pair (x;y) and you never finish working out y also
- You multiply x-values in your head when you should add them
So make a list of all the usual mistakes you make and write down how to fix them or what you should do instead. Then go through that list after completing an exercise to check
whether you’ve made some of your usual mistakes and fix them. You can also revise the list before every test and exam to make yourself aware of the mistakes.
This way you train your brain to not lose marks on silly little mistakes.
