I saw this search term, and figured that is one question that just cannot go unanswered:
1. Go to http://www.topik.go.kr.
2. Click on the icon that looks like a man facing left.
3. Depending on whether you sat the TOPIK in Korea or abroad, click on the Korean flag or the icon depicting a bunch of happy foreign Korean learners.
4. Type in your candidate number and birthday
5. Click search and voilà there is your TOPIK score!
I hope you did well!
