There are some major difference with 5e compared to 3.5/PF. It would probably help if you read up on some of the rules; fortunately, there's an SRD for 5e so that might help. I'd also take a look at the sheet on Mythweavers for 5e so you can see the differences; it does a decent job laying them out.
