Tips and tricks to ace the 2020 O/L Maths paper




Review the concepts and formulas before the exam




One of the most important things to do before the exam is to review the concepts and formulas that you have learned throughout the course. You can use your notes, textbooks, past papers, or online resources to refresh your memory and understanding. You can also make a summary sheet or flashcards with the key points and formulas for each topic. This will help you to recall them quickly and easily during the exam.


Read the questions carefully and show your work




Another crucial thing to do during the exam is to read the questions carefully and show your work. You should pay attention to the keywords, instructions, and units in each question. You should also check if the question has more than one part or requires more than one answer. You should show your work clearly and neatly for each question. You should write down all the steps and calculations that you do, even if they seem obvious or simple. You should also label your answers with appropriate units and symbols. This will help you to avoid mistakes and earn marks for working.


Use a calculator wisely and check your answers




A third useful thing to do during the exam is to use a calculator wisely and check your answers. You should use a calculator only when it is necessary or allowed. You should not rely on it for simple calculations or mental arithmetic. You should also be careful with rounding off numbers or using fractions or decimals. You should check if your answers are reasonable and consistent with the given information. You should also check if your answers match the units and format required by the question.


Manage your time and skip difficult questions




A fourth helpful thing to do during the exam is to manage your time and skip difficult questions. You should allocate your time according to the marks and difficulty of each question. You should not spend too much time on one question or part of a question. You should also skip any question that you find too hard or confusing. You can come back to it later if you have time left. You should try to attempt as many questions as possible and not leave any blank spaces.
