Krishna looked at the data streams that Tally sent him. The group that she was grading did seem to have an unusual amount of right answers. Heck he expected near perfect from Blackfern and he hadn't disappointed so far. This though was unusual. He typed back, I agree that this is unusual. Give me the IDs of the test takers. I'll compare with their school records.
That was the first step. He could scan the cadets for any discrepancies and then he'll have Cul summon them to the Commandant's. Of course leaving them with Cul would give the would be cheaters a different look at the world.
I would expect good scores coming from the group you inspected this morning Tally but I want to make sure on this batch. If there are any more, book mark them.
