Try before you peek
Work through a question before opening its mark scheme. Use the duration printed on the paper for a timed attempt, or take one section at a time while you are learning.
Turn a mistake into a next step
Compare your working with the matching mark scheme. Note the idea or step you missed, revisit it, and try a similar question without the solution. A raw practice mark is not an official grade.
