Hello Praveen. Thanks for contacting Careers360 and we hope we will be able to answer your query.

An intensive Google Search yielded no results. But, the question is immaterial. Can you please tell me why do you care about how many students wrote BITS HD?

It all depends on your willpower and the skill and the motivation to succeed. Nevertheless, I would like to direct your attention to this link for more information about the exam:

Please note that applications close quickly. Hope this helps you and all the best!
