A very strange moment of my life

Today, after the class was over, when I was passing the intra (?) road of the college, there, I saw some of college students (because you said that there are some college students, you must add ''s'' and that is expressing plural nouns) of different branch were fighting one of my college (I don't understand the point of this sentence).There I went and asked of what the matter was, the people (it can be also just they and we will know that they are the people and if you want to mention that about the people you will say ''the'' in front) didn't listen to me and start to fight with me too. At once I got anger and I select one of them to beat very badly (This sentence is correct, but it would look much better if you wrote it like this: ''In one moment I got angry as well and I started beating hardly one of the guys''). Then the remaining friend of him came there to save him.

-When you write ''I'' remember you never write small ''i'', but big one ''I''.

-The '',.'' and other symbols like this are usually written next to the word and after that you do place and write next. ex. ''Yes, thanks.''

-The inital letter in the sentence MUST be capitalized.
