Just like Jee main, you will be getting 3 attempts to crack NEET exam as per the information out in 2017 as Earlier, CBSE had said that the number of attempts a candidate can avail at NEET is limited to three and candidates who had already exhausted their three attempts will not be eligible to appear in NEET 2017. However, as per a new notification released on February 3, 2017, CBSE has rolled back a limitation of three attempts and the examination taken in 2017 will be treated as the first attempt irespective of previous attempts.

Hope this helps!!!

You can take NEET 3 times according to the new change in 2017.

2017 will count as your first attempt  irespective of previous attempts if you have appeared in the exam.

Good Luck!!
