CareerOrbits is a very useful preparation tool for NEET aspirants. I had opted for NEET Online Test Series 2019 - Ultra version with Practice Question Bank. It has got a wide variety of questions with detailed explanations for each of them.
The questions in the practice question bank, chapter tests, and mock tests are very similar in pattern to the actual NEET exam. This has immensely helped me in getting admission to get admission to Calcutta National Medical College (CNMC).
Overall, I would definitely recommend it to my juniors who wish to crack NEET.
