Hi,

Hope you are safe and doing good. Regarding your concern NCERT at your fingertips is for practicing NCERT based questions while neet guide is for a more firm grip on practicing questions.

You must first do NCERT at your fingertips and if time permits you can do neet guide or dc pandey physics or anyMTG objective book if you find suitable. If you want to have a look at neet guide see it on YouTube.

Hope this helps, All the best
