I think that the word university must be capitalized in case only when it is just a proper name. Unfortunately, I found it capitalized at this site being started with upper case while even though it is still not functioning as a proper name.
Please see my amendments to your post above. Check on your use of "in case" and "just" in the first sentence, and "while" and "still" in the second sentence. It's good that you try to use these phrases but, in this particular case, you did not use them correctly.
I have left "proper name" but remember that you will hear/see "proper noun".
Remember - correct capitalisation, punctuation and spacing make posts much easier to read.
