Advance Mathematics Test - Episode 1: Real Numbers, Decimals & Significant Figures for FODE and Upper Secondary Students

Students in Papua New Guinea who are studying through FODE and also in Upper Secondary school system can greatly benefit from taking these tests because they strengthen their understanding of core mathematics topics that are essential for advanced mathematics and national examinations. Topics such as real numbers, recurring and non-recurring decimals, and significant figures form the foundation of algebra, measurement, and problem-solving skills tested in national exams. By practising multiple-choice questions regularly, students can improve their accuracy, speed, and confidence when answering exam-style questions, especially in a self-study environment like FODE where independent learning is important. These tests also help students identify weak areas early, allowing them to revise difficult concepts before examinations. For Upper Secondary students preparing for national assessments, mastering these basics supports higher-level topics such as scientific calculations, equations, and data analysis. Overall, consistent practice with structured tests enables FODE and Upper Secondary learners in PNG to build strong mathematical thinking, reduce exam anxiety, and increase their chances of achieving better results in national mathematics examinations.
