Remember to use quotation marks when someone is talking. Or barking. 
You could also split the paragraphs into smaller ones.
Overall, I agree. This is definitely one of your better pieces. Could use a bit more creativity/originality though.
Hey colours!
Thanks for your continuous support and your quick tips.
I am reviewing them right now, and I absolutely agree with what you've said.

Good piece, relevant to the prompt. I like it. There are some details that don't aid in the progression of your story though. Keep this in mind. Every word counts when you're writing with such a limited word count. Some minor grammatical issues - make sure you allocate time to proofread. There is little use of literary techniques - work on this. Take a look at this website http://literarydevices.net/#gti_S and make note to include some devices. This will really develop your writing making for an overall stronger piece. Another very important thing to remember is show, don't tell and be consistent! 
Hey coffee,
I find myself saying this a lot lately but thanks so much!

It really means something to me, to have someone as detailed as you correct my essay.
I really appreciate your corrections and I have undoubtedly learnt from your corrections.
Your time was not wasted marking my essay!

Hi guys!

Once again thanks for everyone's continuous support, I find myself improving a lot with you friendly bunch helping me out!
Here's today's narrative essay. I wrote this one in 15 minutes and a bit.
I was like DAAMMIT when the buzzer rand and I was on my last sentence.
Anyway, the prompt was:
Should state colleges be free?My only concern with this piece is that I forgot to include my linking sentence I think? I don't know what it really is except that it's important
Like always, everything under the dotted line is what I actually wrote so grammatical errors are all not typos and what I actually did.

I have two main questions, if anyone can be bothered.
1. Did I start off my conclusion right? If not, what's the proper way?
2. The linking sentence issue, what is it and did I do it. If not what's the proper way?
Danke sehr!(lol, thank you but I felt like practising German)

In our educated soceity, a state college is now an essential part of a student's life. The ongoing topic of whether state colleges be free to attend is a discussion both in the local schoolyard and in confidential meetings involving the prime minister. Free state colleges will ease the extremely high pressure on students, will not cost the government much money contrary to popular belief and is a crucial part of a person's life. State colleges should undoubtedly be free to attend.
To start off, making statue colleges free will drastically lower the amount of pressure on young students. Imagine one you just came out of college, under huge debt and unemployed how could a student possibly deal with so much financial stress at such a young age. Making state colleges free will in return make the harsh lives of college students much easier.
In addition, college is a crucial part of one's life. When one gets to college, it is not simply a place for learning, state college is a place where one mentally grows up. In college, one learns to solve problems that are encountered in real life, making college paramount. The high cost is usually why one may not choose to go to college. If we make state colleges free, we will develop more life smart students.
While some may argue that such change will bankrupt the government, one see the truth when one realise that if more people go to college, a nation will have more educated people earning more funds for the government.
State colleges should unequivocally be free because they reduce the mountain of stress young people face while learning college, educates students about how to deal with practicle problems and will not cost the government. State colleges should undoubtedly be free.
