When I studied engineering in India, we never put our names in the finals at college. Every one gets a exam id and that goes in the answer sheets.

Also, it is never your professor who grades you - the answer sheets are collected and lecturers/professors will correct them at the state level across all the engineering colleges in my state.

I do not know how it is now as there has been an explosion of colleges in the state. But expect the standardized tests are similarly conducted.
