For people coming in from Engineering, Arts, or Nussuland and going to Faculty of Science in NUS.
1. The bridge links Engineering and the libraries. Go to the east (libraries') end. There you will find LT4. LT4 has a back door. Go to the right of the back door. You find a place called CDTL, the Centre for Development for Teaching and Learning, but as far as I have asked no one really knows what the hell the place is supposed to be for. Upper Kent Ridge road starts here.
2. Pass by the Acoustic Labs and the Centre for Protective Studies, namely the place where they explode all the things. Pass the Y-junction.
3. To the left and right, there are steps that lead down, paved by bricks. Take the left one to S1. At the time of writing, much of S1/S2/S3 are under renovation. Turn right into S2. Pass by the Biological Sciences offices, some of which are staying in the building.
4. Pass by the Chemistry tutors' offices. Enter the Pharmacy labs. Today I could see some of the undergrads at work and minding their own business. I felt a bit strange because I have always enjoyed doing my own labs undisturbed by outsiders (E3A is very isolated corridors-wise). From time to time one of them would look up at me with a puzzled expression. I left that place quickly.
5. Take the stairs 1 floor down to Science Library entrance.
