which section do u think is advisable?
I also have similar question for university entrance rank

If you have decided to mention it in your CV, the most appropriate section would be honors and awards. The main focus of my sentence was on "not impressive" not the "honors section".That is, i think your rank among less than 20 people is not worth of mentioning no matter in which part.

Regarding your second question, it depends on your university and your rank. I put it myself like this:
Ranked top 1%among... in honors section
