Vyntex CBC Centre has started to publish Junior secondary schools Question Answers revision encyclopedias booklets in each learning area which exhaustively provides all possible forms of questions and comprehensive answers topic by topic in a much simplified way. Each booklet has only one learning area covering grade 7 to 9 work. We have provided as many answers as possible to our learners for faster and efficient revision. These are the best books for JSS learners especially Grade 9 candidates.
