NEB chemistry — common questions
Which NEB classes does ChemSchool cover?
National Examinations Board chemistry is covered for Grade 11 and Grade 12. Each has its own notes, past papers and syllabus, kept separate so you only ever see material for your own class.
Are the NEB chemistry notes and past papers free?
Yes. Every NEB chapter, past paper and mark scheme on ChemSchool is free to read online or download, and you do not need an account to open them.
Which years of NEB chemistry past papers are available?
Papers currently span 2021-2081, and new sessions are added as the board releases them. Older sessions stay online, so you can work backwards through several years.
How are the NEB chemistry notes organised?
Notes are split by class and then chapter by chapter, following the order of the NEB specification, so a chapter page matches a single syllabus section rather than a whole unit.
