Type a 100-word reflection for today's lesson.

DAY 2: 26 May

Type a 100-word reflection for today's lesson and comment on your work.

I feel that today's work was extremely hard and I did not complete it within the 1 hour timeframe, which included today morning, 7.30 till now at 12.00, I am not so sure whether that is 1 hour :) I have done it with the discussion of my classmates on MSN. Many of themn are not up to expectations and the basic design is still there :)

Equations
Syringe
