Generate JAMB Chemistry CBT practice from notes on reactions, calculations, bonding, and organic chemistry.
The JAMB Chemistry CBT Generator helps UTME science candidates create focused Chemistry practice from their own notes. Upload tutorial-centre handouts, PDFs, textbook summaries, reaction notes, or corrected past-question explanations and generate CBT-style objective questions with answers. It is useful for atomic structure, bonding, periodic trends, mole concept, acids and bases, electrolysis, organic chemistry, rates, equilibrium, and qualitative analysis. Students can practise quick option elimination and review explanations after each question. Tutors can also create Chemistry drills from the specific topic taught in class, making JAMB preparation more targeted than random question banks.
