Yes, it is perfectly okay to appear for the NEET (National Eligibility cum Entrance Test) at the age of 22. There is no upper age limit for NEET, allowing candidates to take the exam as long as they meet the eligibility criteria, which includes having completed their higher secondary education (Class 12) with the required subjects (Biology, Physics, and Chemistry). Many students choose to take NEET a bit later, especially if they are pursuing other interests or need additional time to prepare and its okay at the end you will become doctor only that matters.
