Hello aspirant

No, frog and earthworm are not included in NEET syllabus of biology, in your NEET syllabus there is only brief account on the digestive, circulatory, respiratory, nervous and reproductive for cockroach only.

But it has been seen that many times questions in NEET have been asked from earthworm and frog, for example in NEET 2017 questions were asked from frog.

So it's better if you study , frog and earthworm as well for your neet 2020 examination.

I hope that you find this helpful

Thankyou
