Why are you selecting this major?
From the time i started Chemistry in 10th grade, it has been my favorite subject. I find it fascinating that most things around us revolve around chemistry. I also love that there are so many different fields of chemistry such as: forensic chemistry, cosmetic chemistry and my favorite Pharmacy. Majoring in Chemistry will allow me to become prepared for a career in Pharmacy.
Is the grammar correct or are there some mistakes?
the capitalization is a bit confusing. it just looks strange that you capitalize the word 'Chemistry' in the first sentence and then stop until the last one. also, not sure pharmacy needs to be capitalized. and isn't pharmacy a field of many sciences, including biology and chemistry?
Not to point out the obvious but this is a short essay. In these very short essays, I think it is best to be very specific about one point. So instead of talking about a bunch of different fields of science. Just start with I like pharmacy or something like that and then explain why pharmacy is awesome. I know that is basically asking you to redo this essay, but since its so short, I'm hoping that its alright.
