Update - completed derviative

I completed Derivative today. Now, it is time to proceed to Alternative investment. Should't be too difficult since there are only two readings.

Increasing physical stamina cannot be overemphased. Yesterday morning, I swam 16 lengths breaststoke while my son was having his usual swimming class. Swimming 16 lenghts is breaking my own personal record! I also feel much more in energy and perhaps that's why my absorption rate is higher for this CFA study.
