Maths Trail

Today there are two tests -- Infocomm Studies and Geography. I think I did quite well for IS but not for Geography(I think I will at most get a B4 only) .
Next is the Project's Day Prelims 2. My group consists of Wei Xiang, Tian Hao, Ernest and me. I think we failed it (again). If we really failed it, we would get no ACE points for this project but we have to continue doing it as it is an IRS project too (a compusory thing for all Ispark).
Then after the PDP2, Wei Xiang, Ernest and I went for the Maths Trail. As we need 1 more member, Ernest asked Brolin to join us. The Maths Trail started at 3pm to around 5pm.
There are a few stations for this Maths Trail. My group's first station was the Swimming Complex. (The clue was "Splash".) We had to find out the capacity of the pool.
The next station, in front of the Tan Kah Kee statue (clue was "Founders".), we had to find out the height of the Clock Tower. Then, we were given the clue "The vein between Block A & B". The problem given to us at that station was to find out the no. of ways to travel from Point A to Point B.
The next station was at the canteen (clue was "Recess") and we have to find the sitting capacity of the canteen.
We were given the clue "The last class of the first", and my group immediately went to 1N.We had to create magic squares of sides 3, 4, 5 and 6. We only managed to complete the 3-sided square.N+N was the next clue. N+N=...2N ! We went to classroom 2N and had to do a Sudoku puzzle.After that, we went to the table tennis tables near the canteen as the next clue is "Ping Pong".We had to solve 4 questions before we were given the next clue "Race, Language or Religion".
We went to the terraces and were given another question to solve.As this is the last station, we ran back to the library (Ernest was walking until the last part).We handed in the answer sheet and went home.
