"Catch up" means to reach the same level as other people who have progressed further or done more than you. For example, if you miss a few days of school or work, you need to catch up on the work you missed so you can be at the same level as everyone else. You can also use "catch up" to mean reconnecting with someone you haven't seen or talked to in a long time. For example, you might say "Let's catch up over lunch" to a friend you haven't seen in a while.
