Due to the nature of my profession, I have been asked a particular question for umpteen times. The question is “Which science should I take?”. Often, I find myself struggling with an internal fight between the holistic me and the practical me.
The holistic me will advise the inquirer to check out the contents of the three sciences – Physics, Chemistry and Biology. Knowing what each science is dealing with, the inquirer can make an informed choice or so to speak. Thus, interest and aptitude will go hand in hand during the process of decision-making.
The practical me will advise the inquirer to choose the one that he or she is better in. Period. No love, no interest, simply the one that offers the highest probability of getting a good grade.
So in conclusion? Well it depends on what your goals are. Both short-term and long-term goals.
Frankly speaking, you can always start learning any of the sciences at any age. It is a matter of time and dedication.
