surprise "surprise test"

Just finished surprise test. Idea of surprise test was that it can happen any time and subject will be random. School gave time table for test but I was absent that day because of travel/sickness. Suddenly we had a test and mother got call from school that why didn't she come to pick up me since it was test. The fact of matter was that mother never knew there was test! She got surprised because English paper was already over!! My parents are really dumb even though they drop and pick me from school, never communicate with other parents, although sometimes mother do talk with teacher.

Since timetable got revealed next two days I have to study since they came to know about test and I am very sad since they came to know about tests :( and I have to study!
