What's "rediscover" mean in here?

To "rediscover" something means to discover again or find out again about that one thing. For example, let's say there was a movie you really enjoyed when you were 18. You forgot about it and found it again when you were 25. That is called "rediscovering" something. Remember that the prefix "re-" has the meaning of "again" or "again and again" to indicate repetition. Ex: I'm going to redesign this structure. It needs a lot of fixing. Ex: I got a lot of answers wrong on my exam, so I will be doing a lot of revision in my free time.
