biodiversity. OPEN BOOK EXAM. it wasn't exactly a new thing to me. i had a similiar experience back in secondary sch. it was a geog test. everyone flunked coz there was no time to check for the answers and copy them down word for word. the trick to OPEN BOOK EXAM is the answers can never be found in references directly. as i had expected. "study like never study". luckily i remembered to put on my thinking cap. glad i'm quite smart. otherwise i would have handed in a blank answer script. 2 up, 3 more to go!
