Hello aspirant , earlier it was decided that any student can appear for NEET UG for only 3 time . General student can appeared for 3 times up till 25 years and reserved OBC /SC/ ST students can appeared for 3 time till 30 years. Now the system has changed , any student from any category can appear for NEET any Number of times and there is no age limit . Te lowers age limit is has been kept same ( 17 year old )
