Hi College Girl,

You will probably agree that is much more important to learn how to do something yourself instead of having a person doing the work for you. So, what I'll do is the following:
I'll list all words you spelled in your own individual way. Please, try to check the spelling of these words and correct them yourself:

• your (is that good English?)
  
• i (you know what's should be improved here)
  
• im (actually, that's a German preposition)
  
• univercity (interesting new word)
  
• theres (here an apostrophe is missing)
  
• icant (these are two separate words and an apostrophe is missing)
  
• u (the personal pronoun you have in mind consists of three letters)
  
• writting (one letter too many)
  
• greatfull (please, check this word in Google)
  

As for the word reemerged — it's a verb and it means «to appear again». For example: «Many previously known diseases have reemerged». or «The software has reemerged with a new look».

Please, let me know what you think and also if you can find the correct spelling of the words listed above.

Hi College Girl,

So, you know how to spell words correctly, now you should try to stick to the correct spelling ('you' instead of 'u', 'I' instead of 'i' ect.)
Of course we are here to guide and assist you so that you will become your own leader.
