我學中文嘅小故仔 (Attempting spoken Cantonese)

三年以前, 我喺大學開始學習中文. 我記得我第一嘅次上課, 真喺好興奮! 我認識咗好多中國朋友, 我跟同我D朋友仔一齊學英語文同普通話, 同埋佢哋語言交換. 如果我呢個時間候冇朋友幫我學習中文, 我一實會停學中文. 而家因为宜家我畢咗業咗, 而佢哋都返晒去中國啦.

學習語言唔容易，但係我覺得學習跟向朋友仔學習係一個好方法學會語言嘅好办法．：）

Please pay attention to you punctuation.

" , " should be "，”

" . " should be " 。”

Hope u could stick to it , Fighting(cheer) !!!

三年以前, 我喺大學開始學習中文. 我記得我第一嘅次上堂, 真係好興奮! 我認識咗好多中國朋友, 我同我朋友們一齊學習英語同普通話, 同埋交換語言. 如果我個陣時冇朋友幫我學習中文, 我一實會停學中文. 而家我畢咗業, 佢哋都返左去中國.

學習語言唔容易，但係我覺得同朋友一齊學習係一個好方法去學識語言．：）

1. 故仔 - 仔 itself serves as a diminutive suffix. So 小 can be omitted.

2. 個陣時 - I guess you wanted to say "at that time"  in the text. If so, 個陣時 can better express such meaning. 呢個 mostly refers to "this" so it may not be a good choice when talking about the past.
3. 畢咗業 - The use of 咗 usually comes right after the verb instead of the phrase e.g. 做咗功課, 食咗野 

Good writing. Keep it up! Cheers

You did well! In Cantonese you may use 同 more often, and the plural "們" is seldom used in Cantonese. Keep it up :-D !
