Science and geography tests

On tuesday would be my science and geography tests! I am now biting my nails and praying to god to let me pass this test. I was already sad enough when i received my maths paper, scoring a mark below expectations. Now comes what is like "hell in all its fury" to me. Double tests on one day! I was not exceptionally good at science but still did okay. I bet the science test would be very difficult and i would have problems passing it with flying colours. To be honest, i only got an A for science in PSLE! :( I also did not have an excellent grasp of geography's foundation. Having started off shakily, i pulled up my socks and finally knew how to solve geography related questions. Now, there will be two tests on same day and i would need all the luck i have to get a satisfactory mark in both tests. Time is running low. I will have to really study my head off if i have too. :)
