Hello, We use the word "over" when something is more general and the word "into" when something is more detailed. Some examples: I want to go over the plan for tomorrow. I want to go into the details of what we are doing tomorrow. I want to look over some properties for sale. I want to look into buying this house. Hope this helps!
