Hi there,
Kcet authorities don't provide the exact data about the number of applied students according to the category but the overall number of candidates applying for KCET in 2017 was 1,85,418 out of which 1,79,000 appeared for the test and around 1,26,000 cleared the exam.
There has not been a clear view over the statistics of 2018 but an estimated 1,98,536 students appeared for the exam.
