Hello there ,

Hope you are doing well . See , Vishram Singh for anatomy set has 4 main textbooks  alongwith a textbook for neuroanatomy . So , if you want to start reading before the session of 1st year professional M.B.B.S. begins and for studying all round the year , you'll need the main books set which has 4 volumes and the neuroanatomy books .

The prep manual i.e. the book named Selective Anatomy by Vishram Singh just covers the important topics in short and you can use that before revision right before your exams in college but for studying in-depth the whole year ,you have to buy the full set .

Hope my answer helped.
