"A science that relied on quantiative analysis..." - Columbia Engineering Supplement

Okay, so I've worked on the first paragraph of my Columbia Engineering essay and I need help with condensing it. Currently it is 947 characters long and I need to make it about 750 or so... Any comments, suggestions, and corrections are appreciated. Thank You!!

"Chemistry is an exact science." At the time, I did not know what my AP chemistry teacher meant by that statement. I was reluctant to acknowledge its significance until I was obligated to apply it practically. One day, in the midst of a lab experiment that involved titration, I accidentally added too much base to the unknown acid which made it over concentrated. Although I felt it didn't make much of a difference, my teacher exclaimed that by over diluting the solution, I had ruined the purpose of the lab. This is when I apprehended what was meant by an "exact science." Preciseness and accuracy were key components into making chemistry what it really was - a science that relied on quantitative analysis just as much as it did on qualitative analysis. It was then that I realized that I wanted further explore the essential concepts of chemistry without any limitations. I knew that this would only be possible through chemical engineering.

Hi,
I made it as short as I could and corrected some gramatical mistakes.

Good luck with your apps :)
Btw, can you also check mine? Thanks!

Thank You! I will correct it right away!
Any other suggestions, corrections, or fixes appreciated!!

over-concentrated

Would you care to provide feedback on my essays, too? ;)

hey guys!
Here is the entire essay:

"Chemistry is an exact science." I did not know what my teacher meant by that statement and I wasn't able to understand its implications until I applied it practically. During a titration lab, I accidently added an excess of base to an unknown acid which made it too concentrated. Although I felt it didn't make any difference, my teacher exclaimed that I had ruined the purpose of the lab. This is when I understood what was meant by an "exact science." Precision and accuracy are key components to making chemistry what it really is - a science that relies on both quantitative and qualitative analysis. It was then that I realized that I wanted to further explore concepts of chemistry without any limitations, which would only be possible through chemical engineering.

I am interested in the study of engineering because I can use my own creativity to create and develop a conceptual idea that can be used to solve problems in real life. As a person who has continually used home-made appliances to perform chemical experiments, taken apart and rebuilt computers to decipher their anatomy, and reprogrammed devices out of curiosity, engineering will further allow me to question the unknown and enhance my ability to perceive and interpret new knowledge. Though my job as a chemical engineer will be different from that of other engineers - creating pharmaceuticals and producing sustainable energy - I look forward to working with people who have similar interests, and different specialties, to accomplish a common goal.

Please help me fix it!! I don't have much time!!!!
