The three question papers are of physical education exams of Dhaka and Barisal boards, and Dhaka board physics exams.
A child journalist at bdnews24.com's Hello page, who is taking the SSC exams this year, has unearthed the latest leak.
The Barisal board physical education exam questions were out on another Facebook page 'Ssc out Question Bank 2017' on the same night.
The child journalist received the Dhaka board physics question paper on Wednesday night through messaging app WhatsApp in a similar approach used by bdnews24.com earlier to find the leak of Dhaka board math test. The physics test was held on Thursday.
All the leaked questions were exactly the same used in the tests.
After Sunday's revelation of the Dhaka board math question paper leak, Tapan had admitted that the questions received half an hour before the test matched with those used in the exam.
Education Minister Nurul Islam Nahid and the officials in his ministry then said they were investigating the matter.
Asked about the investigation, Tapan on Thursday said, "It is under way."
Dhaka board Chairman Professor Mahbubur Rahman received bdnews24.com's call on his mobile phone later in the night, but once he knew where the call came from, he said he "could not speak at that time because he was busy at a function".
After bdnews24.com published the leak report on Sunday, he said the government will postpone test if question paper leak is proved before it is held, or cancel it in case of finding proof afterwards.
Later, his comments indicated he backed away from the stance.
