Do I need any other books for the NEET apart from the NCERT and Aakash study package? If yes, what are these books?

For neet 2020 stay focussed with what you have. Do mock tests daily and perform remedial studies. If one wants top score doing jee questions of the past is a good idea. Ensure you cover AIIMS previous year questions too. For 2021 do refer campbell or Trueman for biology. Physics H C Verma and chemistry Solomon fryhle for organic help. Mukherjee is a good book for physical chemistry. Refer to recent trends on ecology events in India like endangered species tiger population etc. Corona virus related information is important.
