I am busy this week. I had SPA today, and will be having on Friday (2 of them) and next Monday. SMO Senior section was held today, and there is still the Open section tomorrow. Chemistry class on Friday and Geography on next Tuesday. Choir practice this Saturday, most likely.

Anyway, I got D7 for Chinese Prelim 1. 45 marks exactly. So my prediction was wrong anyway (prediction was E8). Well, doesn't matter, I can use Physics, Chemistry, E and A maths to make up for it for L1R5.

Just leave here a maths statement: sin 10° * sin 30° * sin 50° * sin 70° * sin 90° = 1/16 exactly.
