Like I said for one concept there can be a thousand questions, that's why you should do past papers and look at the solutions to see how you can structure your answers in a way that will get you:im pretty sure my maths teacher will say to me, i can actually do those questions but i do NOT show them in the exam. i need to do more practice questions, and make sure that i know when to use them. What i think is that my maths teacher is right but i just find the questions in the test challenging.
1) All the marks if it's worth greater than one mark
2) Full marks the next time you come across the question
Also if you notice that you forget how to solve the same type of question over and over again write it down in a notebook and look over it daily/weekly so that you remember how to approach the question
