There is nothing wrong with that at all. Especially since that is what you get certified to do. In fact the shop I help teach at, we do 5 check out dives. The first 4 are with an instructor and DiveCon if one is with the class then on the 5th dive while the instructors are finishing up the paper work we have the students plan and execute a dive with their buddy. Granted there are still experienced dive professionals on site for the 5th dive, the students are out on their own (with their buddy of course) just diving and having fun and working on the skills they have been taught.
