You must study hard in order to pass in the examination. (Make it compound)

“I make him do the work.” এখানে ‘make’ verb এর পরে ‘do’ bare infinitive হিসেবে ব্যবহৃত হয়েছে।
কিন্তু Passive voice এ এটা bare infinitive থাকবে না, to যুক্ত infinitive হিসেবে ব্যবহৃত হবে।
তাই সঠিক voice change হলো ‘He was made to do the work by me’.
I make him do the work - He was made to do the work by me.
