Can someone please proof my essay? (it's for college)?

I have received many achievements and have had many wonderful experiments to share. Though, none compares to making the Principal's Honor Roll ( Straight B'S my first semester of my senior year) . Over the course, of the first semester, I cried, laughed, and was frustrated many times. I found hardships in a lot of areas and often doubted my abilities to triumph and succeed. Even though, In the end, I did succeed. An English cl, particularly, gave me trouble. Despite, the fact, English is my favorite subject. The cl has taught me to not procrastinate and to apply my self, being organized all over in each part of my life. Senior year has been a rocket mountain. Yet, I never let my failures determine my next step. Instead, I allow my failures to teach me a lesson, and a different approach for the next time. I've come along way from when I was a freshmen, to now a senior. Over the years, my attitude and priories have changed. I now understand, the essence of taking your education seriously and what happens when you do not, due to laziness and a careless attitude. I have reached my goal so far, but I won't let my pride get in the way and stop there, I will continue to receive good grades for the rest of my senior year. I will leave high school feeling accomplished. I may not be where I started, but I will not ruin a second chance, I am given. Nothing can get in my way. Not even frustration, tears, or laziness, the only thing that might effect me is my determination and lack of sleep. But, in the end, It will pay of in each semester. Hopefully, I still have the same ambitions, once I am freshmen in college and will continue to achieve wonderful grades, that I've earned proudly.
