Most klass questions are written for klass. Some are adapted from openly licensed teaching material: we took the original question and rewrote it in JAMB and WAEC style, with four options, then filed it under a JAMB or WAEC topic and checked it before it went into the bank. The wording, options and worked solution may differ from the original. We keep a record of the source of every adapted question.
