Abuja — The West African Examinations Council (WAEC) has postponed the full implementation of the computer-based test (CBT) format for the 2026 Senior School Certificate Examination (SSCE) until 2027, according to a statement released at the council’s 63rd annual meeting in Umuahia, Abia State. Hajia Binta Abdulkadir, Chairman of WAEC’s Nigeria National Committee, explained that the 2026 May/June edition will now serve as a pilot phase — allowing candidates to sit for either the traditional paper-and-pen test or the digital format. She emphasized that no student will be disadvantaged by the transition. The delay follows widespread concern over the readiness of many schools, particularly in rural areas, for full digital exams. Many institutions lack adequate computers, reliable electricity, internet connectivity, and trained personnel—factors WAEC and the Federal Ministry of Education say are essential for a successful rollout. To facilitate the switch, WAEC co...
Quantitative analysis deals with the determination of the amount of each component in a sample of matter. It is divided into two which include: a. Gravimetric analysis b. Volumetric analysis Gravimetric analysis : is interested in the measurement of mass of the substances. Volumetric analysis : is interested in the measurement of the volume of solutions. Titration is the method used in volumetric analysis. This is done by careful addition of standard solution from a graduated container until the reaction is complete. A complete reaction is indicated by a colour change in the resulting solution. Some apparatus used for volumetric analysis These are burette, pipette, conical flask, beaker, funnel, wash bottle and volumetric flask. Standard solution is a solution of a known concentration. Basic Principles of Volumetric Analysis Test substance or analyte, is normally a base in acid-base titration, is pipetted into the co...
