Can someone correct the grammar?

Hey! I was applying to a college and they require me to write a statement of purpose. I wrote these two paragraphs. Can someone correct me if there is any grammatical mistake? (I am not a native speaker.) :

Para1: "Physics has always been an adventurous feat to me. As my knowledge in Physics grew, I gradually developed multiple perspective to the world around me. Those new perspectives helped shape my aptitude for science and also increased my knowledge.
I also love the integrity of Physics and Mathematics, both being my favorite areas of Natural Sciences. I am equally competent in both Modern and Classical Physics, but I prefer Modern Physics. Reason being, It requires complex mathematics and has underlying secrets, yet to be discovered.
Studying Physics at higher level would enable me explore it at even deeper level."

Para2: "I fell in love with Mathematics when I realized that there is more to Maths than just Addition and Multiplication. It was the time when I went to my 8th standard and encountered the world of Pure Algebra. I liked the challenge, the clarity and the fact that in Mathematics nothing is ambiguous.
My area of expertise includes Calculus, Trigonometry and Graph Theory, although I am equally proficient in Complex Algebra and Real Number Theory.
Studying Mathematics at even higher level would enable me to satisfy my curiosity for exploring its various forms, I am not aware of even now."
