"I come, I came and I concer": Lady says as she celebrates after her final exams

Come on! Are these people joking or do they really mean what they write?
A Polytechnic graduate took to Facebook to celebrate after writing her final exams but she made a blunder that has given her post attention.
Sharing a photo of herself and coursemates, she wrote: "I come I came and I concer".

Obviously, she meant "I came, I saw, I conquered". She will not be the first to make such a mistake. Just a month ago, a university graduate while rejoicing after writing his final exams also made a similar blunder. Is this a sign that something is seriously wrong with the education system in Nigeria?
