I will say its too much for NEET , I have solved both parts and most of the questions 40% are out of syllabus but don’t get disheartened they will be helpful for you to crack aiims for sure, I solved both books and then attempted aiims biology paper it was like a cakewalk for me. Mind my words it is a good book but if you have less time then don’t go for it, it will take at least take 2 months for you to solve if you don’t do other subjects parallely . I did it as I’m a dropper.
Conclusion: if u have ample of time and focusing more on aiims than do it for sure it will help, if its just about neet then even ncert and some other books like ncert at fingertips will be more than sufficient.
Other people here don’t know because they haven’t used it, whatever I have wrote is from my own experience
Hope it helps!
