"Catch up with" is a very common expression that means to meet up with someone or something that you have fallen behind with. For example, if you haven't seen a friend in a long time and you want to spend time with them, you might say "I need to catch up with my friend." Or if you are behind on your work at school, you might say "I have a lot of catching up to do." Basically, it means to get up to date and catch up on what you've missed.
