Term 3 Science Test

Last science test before the End-of-year (EOY)paper. Wasn't too pleased with my result, considering the fact that I fared below my expectations.
Didn't revise properly, really.
First, optics. Did not revise the definitions of virtual and real images. Did not really go in depth into the revision of colours. Did not memorise the types of images that can be produced by the convex lens. Honestly the questions on optics were really free marks to be given away. ALL the questions have appeared in the worksheets that I did before, and mere redoing of those would probably give me (in fact, anyone) full marks.
Now to ecology. I realise, biology has been my Achilles Heel since I flipped open that thick stack of ecology notes. And as I probably would have expected, I did not really fare well in the questions regarding ecology. Furthermore, I had not revised adequately. I merely skimmed through the definitions of habitat, ecosystem, etc. thinking that it would not come out for the test. I was wrong, of course. And that cost me a lot of marks.
I still managed to squeeze through, though, with a A1, though it really was disappointing. I felt that the class performance, too, was rather disappointing. Other than the graph showing the interrelations between the lizard, grass and grasshopper, the rest of the questions were relatively straight forward. I was expecting someone to obtain a full marks. Yet I was wrong. Again.
