Lessons

Lessons learnt:

1) Never, ever take 151e because it took me the same amount of time travelling from school to home during peak hour (the only time it is available) and cost me $2.30 (I didn't know they don't accept concession);

2) Reaching the interchange at 2.40pm, planning to take the 2.45pm bus does not mean that there is a 2.45pm bus;

3) Always print all the notes at one go;

4) My science brain cells are dying.
