Hello everyone,
I wrote a quick paragraph, so I can post it here to see if you guys can spot all the errors in it. I am trying to improve my English , so the first thing I need do find out is what I am doing wrong. Once I figure out where my weak areas are, I am hoping to correct it. Thanks you in advance.

When I was growing up, I always thought I was going to become a field biologist. It made perfect sense. My backyard was my playground. I would spend hours every day collecting, observing, and studying the creatures that crawled, hopped, and scampered in our garden. During the school years, I excelled at every science class I took. I was an honor student in high school who was president of the nature conservation club. I graduated college with a biology degree with a concentration in botany. However, the moment that I realized that my plans since grade school was no longer for me was shocking. As much as I love biology, there was another love in my life. One that I struggle with everyday, English. For me, English was something I struggle with daily. My first language was Vietnamese. Vietnamese is not a Romantic language. We did use plurals or tenses. Two cups of water is two cup of water.
