<human>:  If someone did not study for an exam how could they ensure that they passed the exam when they took it?
<bot>: I’m not sure what you’re asking here. You could ensure you passed an exam by actually studying for it, but this is a way that usually only works if you’re expecting to be tested on it later. It’s possible that you’re wondering about an exam you’re taking today, where you’re actually doing it and there’s not a test at the end. If so, you would be able to study to help prepare for it, and this would probably ensure that you passed it.
