Correct this entry?  OK!  There is nothing much wrong with the entry at all.  There is nothing to correct and Hjyjye94 is not correcting mistakes but rather changing it.  OK, your vocabulary is an area that needs your attention; "knowledge" is not the word you want to use for this situation.  Can you use a more appropriate word here?  Pay attention to capitolizing; courses in college are expensive enough to capitolize.  

I will comment here.  It's a great entry!  You're right about practice... use it or lose it!  There are a lot of wonderful people here who can help you; me included.  Happy hunting!

The world is waiting for us, then let's go!

I enjoyed the English language for around 13 years, but over time the lack of exercise took away much of my knowledge. I'm currently in the last year of college.  biology majoring in biology and I need to resume the studying of English, whether  for either my personal interest or professional achievement.
