Waec Mathematics Syllabus And Topics For 2020
It is no longer news that Waec 2020/2021 registration has begun and the May/June examination is very close. So many Waec candidates have been asking questions about 2020 Waec syllabus and topics to read so as to pass Waec 2020 without much stress.
The truth of the matter is that, the relevance of Jamb syllabus and expo on the topics to focus on cannot be overemphasized. There are four weapons you need you need to pass the WAEC 2020/2021 examination. They are:
RECOMMENDED A. BEST APP TO PASS WAEC AND JAMB B. SSCE, JAMB AND BLOGGING VIDEOS

- Your complete preparation.
In this article, I will bread down the Waec mathematics syllabus for you.

For all papers which involve mathematical calculations, mathematical and statistical tables published for WAEC should be used in the examination room. However, the use of non-programmable, silent and cordless calculator is allowed.
The calculator must not have a paper printout. Where the degree of accuracy is not specified in a question the degree of accuracy expected will be that obtainable from the WAEC mathematical tables.
Trigonometrical tables
in the pamphlet have different columns for decimal fractions of a degree, not for minutes and seconds.
No mathematical tables other than the above may be used in the examination. It is strongly recommended that schools/candidates obtain copies of these tables for use throughout the course.
Candidates should bring rulers, protractors, pair of compasses and set squares for all papers.
They will not be allowed to borrow such instruments and any other materials from other candidates in the examination hall. It should be noted that some questions may prohibit the use of tables and /or calculators. The use of slide rules is not allowed.
AIMS OF THE WAEC MATHEMATICS SYLLABUS
The syllabus is not intended to be used as a teaching syllabus. Teachers are advised to use
their own National teaching syllabuses. The aims of the syllabus are to test:
(i) computational skills;
(ii) the understanding of mathematical concepts and their applications to everyday living;
(iii) the ability to translate problems into mathematical language and solve them with
related mathematical knowledge;
(iv) the ability to be accurate to a degree relevant to the problems at hand;
(v) precise, logical and abstract thinking.
WAEC EXAMINATION FORMAT
There will be two papers both of which must be taken.

Thanks alot sir
This syllabus is good…Asin it even correspond with what we have been taught
thanks,continue the powerful work done
Thanks a lot, you are doing a great job. God will promote you above this. Please can I have an online Tutor?
Thanks
thanks to you all and God would keep giving you knowledge
I love need syllabus for futher mathematics and for mathematics
cul I must learn hard to pass my exams
Thanks flash leaner,but where can I found mirrow of interior.
