Hello

Yes. I have challenged 3 questions in NEET Answer Key though I wanted to challenge 5 ( obviously due to money factor). Fe0 0.98 question from the solid state of chemistry. Find out the pair which contains compounds that are both isostructural and isoelectronic. This question took me 10 minutes in the exam but I couldn't find any such pair in which the compounds were isoelectronic and isostructural. My friends say the official answer to this question is correct but I am not quite convinced. Very low sperm count question from biology. ( I claimed for ICSI & AI both are correct) Now the ones that I didn't challenge though I wanted to.

Ionic mobility question. As everyone is going for it, so I thought I should go for other questions. Sink for Hb question. I honestly don't know the answer to this question. But if you see the Aakash int. NEET explanation video, the teacher said this was one easy question and there was no doubt that the answer was microbes in the soil. So if the experts are so sure, I don't think there is any point challenging this question.
