Distinction starts with the knowledge of what is expected of you in your exams and this video is an highlight of the WAEC WASSCE Mathematics Exam Papers. It gives an overview of the scope of the Mathematics exam, the syllabus and the area of concentrations needed for students to make distinction in their exam.
You know that because it is the mind map of the official WAEC WASSCE Mathematics Syllabus for both School Candidates (May/June) and Private Candidates (February and Nov/Dec) Exams. You can watch this video on the official syllabus itself: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-QtI0O_GWRgA.html
Questions come from the general scheme as highlighted in the syllabus. If you combine that with the trend in past question papers, that should go a long way to prep you effectively for the exam.
After watching this video on your syllabus, I think you can rephrase that statement like this... "The problem used to be that I don't understand Maths. But with this road map, I now know how to embark on my journey to not only understand Maths, but to master it perfectly!" That should be your mindset sis
