What exactly is the difference between 予習 and 復習?

Both are study-related, but they refer to different timing:

• 予習（よしゅう）: preparation before a class or lesson
  
  • e.g. reading the textbook in advance, checking new vocabulary, previewing grammar
• 復習（ふくしゅう）: review after a class or lesson
  
  • e.g. going over your notes, doing practice questions, re-reading what was covered

They’re often used as a set phrase: 予習と復習 = “preparation and review.”

Why is と used between 予習 and 復習? Could it be や instead?

Here, と simply means “and” linking two nouns:

• 予習と復習 = “preparation and review”

You could say 予習や復習, but it slightly changes the nuance:

• A と B: A and B specifically (a complete pair/list)
• A や B: A and B among other similar things (an incomplete list, “A, B, and so on”)

Since 予習と復習 are being contrasted as a clear pair whose balance matters, と is more natural.
