I have one! How high are your schools standards? Because I personally would never give a student an A+ if in many posts they fail to use capital letters for the word, 'I.' Also, why is there a capital letter in the word 'student'? It is hardly a specific name, or the start of a new sentence. You have also failed to use a full-stop after the beginning of your new sentence.

Seriously, don't go acting like you're all smart, mature and amazing unless you are perfect. It doesn't make you likeable.
