[masaegu]

Yes, Kasomi, you may print it out for future reference. The best word for 'corrections' in this case is 添削　（てんさく）, but since it's such a formal word, 訂正　（ていせい） or　直し　（なおし） would be just fine. The other words for 'correction' that you found in the dictionary mean other things.

Keep on studying! I sense a kind of a natural knack for languages in your Japanese.
