3. Create an error statistic for yourself
• Note the errors after a check and find out which error types occur most frequently with you
• Try reducing these common errors by practicing.
4. Create a collection of difficult tasks for yourself
• Use a separate booklet or create a card index.
• Perform a trial exam before an exam.
5. Create a rule booklet for yourself
• Enter rules, formulas, and drawings with sample tasks.
6. Practice again and again in writing
• Practice the tasks step by step.
• Reading and looking through is not enough. Also solve the tasks in writing.
7. Try to apply mathematics practically
• This is also called "carrying mathematics into everyday life". Examples of this are calculating the area and volume of rooms, calculating interest, calculating the sales price without VAT, etc.
8. Design your school materials in a clear way
• Calculate and write cleanly and mark partial and final results (e.g. single or double underline).
• Work through your lesson notes and exercise book entries again at home on the same day and write down questions to the teacher if there's something you don't understand.
