How to determine which of the above is Precast plank and Cast In-situ?

It seems like test when I was on my PDA attachment. I totally had a blast. I requested for structural works as I truly miss those moments when I had casting. Looking back, I cherish those moments. It's like the best experience ever. Because I myself can't believe I actually did it. I mean, come on. A handful of us have tolerance on dealing with the sun, dust and difficult men!

The answer, the smooth finished is the Precast plank while the rough with two joints is the Cast In-situ due to the formwork. Plus, I've just learnt that our BTO floors is partially pre-cast and cast in-situ. Cools!
