I referred Allen materials for biology Is it enough for icar
Hello aspirant. Allen is the leading organisation of coaching for IIT and NEET in India. Both NEET and JEE toppers belong to Allen and most of them in under 100 rank. So you definitely have a wonderful set of weapons (study material). The only thing here is the way you use it. A horse is as good as the jockey. Use it efficiently and you'll achieve success.

Yes it's a good choice. Allen has good study material. Apart from that you can read from physics, chemistry and biology Ncerts of 11th and 12th.
Hope this helps
