The biggest national-level exam – NEET 2022 – concluded on Sunday with over 17 lakh students attending the exam. More than 18.72 lakh students had registered for the medical entrance exam – the highest-ever participation. The majority of candidates took the exam from Jaipur with as many as 52,351 students and the minimum participation was from West Sikkim with 105 students. Similarly, the number of candidates outside India was maximum in Dubai with 646 students and a minimum of six in Thailand.
Most of the candidates who appeared for the exam rated the chemistry section to be the toughest. Further, experts believe that this year’s exam was tougher as it had more statement-based questions which could be tricky for students. This year NTA had increased the time duration and gave 20 minutes extra, however, it also increased the frequency of statement-based questions which required careful reading. In the physics section, students found questions that involved lengthy calculations.
While the official answer key is expected soon, here are official answer keys by coaching institutes –
