The cheaters must repeat a new test all over again for them to prove that they are really worth passing the exam.

Let all of them repeat the exam. Otherwise, there's gonna be another "probe" to find out the cheaters!

amen   the biggest issue here is that to take the licensure exams requires some money. even if the government lets them take it for free, there's always the minute misc stuff to deal with (i.e. board and lodging, re-review expenses) that adds up.

So... maybe just let them pass. And just worry about fixing it for the next batch.

this is really a tough issue and would require a lot of thought on how to be handled.  however, this isn't the main issue.  i guess the focus had been redirected here.  the main culprits are the people on top who handles the exams, the reviewer, and the person who leaked the answer sheet.

right now, it's a losing battle.
