Hi!
I think you should prepare yourself to work hard.. really hard.
The fact that you want to go to the Ibadan University it's really superb! When I was preparing to the uni, i thought that I would do everything by my self, including writing. But it was too hard and I found great helper paperhelps.net . That really makes my studying so much easier and I had really more time to do other things I love.
Good luck!
