In this appealing realm of Chemistry, I am extremely fascinated by the various methods that have been designed to refine the theories and the brilliant achievements that have been applied into our daily life.
I think this first sentence should be more specific. When a reader sees something like this, something that does not tell her anything significant, she stops paying attention. So... can this first sentence name the specific topics within Chem. that particularly interest you?
In my undergraduate years at F University, I got exposed to the entire spectrum of chemistry and developed a solid background in chemistry.
Again, this is very obvious. You are obviously a brilliant thinker, so I challenge you to come up with a sentence that reflects your playful enthusiasm or your serious resolve. Make the reader interested.
With careful consideration,
What careful consideration did you give? I want to know about your specific thoughts and life-strategy. This essay shows that you are a high achiever, but do not rely on that. Make the essay surprising and as unique as you are.
