Essays / Princeton Engineering Essay - three parts of the topic [2]

If you are interested in pursuing a B.S.E. (Bachelor of Science in Engineering) degree, please write a 300-500-word essay describing why you are interested in studying engineering, any experiences in or exposure to engineering you have had, and how you think the programs in engineering offered at Princeton suit your particular interests.

So basically, the topic can be split into three parts:
-why you are interested in studying engineering
- any experiences in or exposure to engineering you have had
-how you think the programs in engineering offered at Princeton suit your particular interests.

If I focus on the first and third part, is it okay if I don't explicitly give examples/proof pertaining to the second part?
