although some chapters are marked but most are still untouched. Books are in good condition like new. Includes all previous year and extra questions and also useful for other exams like aiims paramedical, norcet, nfat, cuet etc. And at last each book have a sampled question paper to solve. The only flaw is that they don't include small chapters like atom, nuclei and semiconductor. Included chapters are mentioned on the front page of book.
