4. OTHER IMPORTANT INFORMATION

(1) Use of Mathematical and Statistical Tables
Mathematics and Statistical tables, published or approved by WAEC, may be used in the examination room. Where the degree of accuracy is not specified in a question, the degree of accuracy expected will be that obtainable from the mathematical tables.

(2) Use of calculators
The use of non-programmable, silent and cordless calculators is allowed. The calculators must, however, not have the capability to print out, nor to receive or send any information. Phones with or without calculators are not allowed.

(3) Other Materials Required for the examination

Candidates should bring rulers, pairs of compasses, protractors, set squares etc, required for papers of the subject. They will not be allowed to borrow such instruments and any other material from other candidates in the examination hall. Graph papers ruled in 2mm squares will be provided for any paper in which it is required.

(4) Disclaimer

In spite of the provisions made in paragraphs 4 (1) and (2) above, it should be noted that some questions may prohibit the use of tables and/or calculators.
