Want to create student cards

Introduction In Powerpoint 2010, if you create a business card, one can also insert a second page to add info at the back and using duplex printing, print a nice business card with information on both sides. i tried it in coreldraw and it works 100% at our college we are also printing student cards. now i want to do it in coreldraw but want like ten cards on one A4 paper. each card on the paper has details and pictures of ten individuals. the problem occurs when i insert a second page with info at the back, and duplex print. the back side doesnt fit correctly as in the case of my business card. and if i make the first size on the page, is there a better way to duplicate it on the page so that the other nine sizes appear neatly?
