[Vocabulary] look over vs go over

[caesar1983]

- This is a very complex computer program. You might need to ............... the instructions again before you get the hang of it.

In this sentence I have to put the correct verb, but I do not have any suggestions...I was thinking about "look over", which means "to examine", but a friend of mine, has written "go over"...which means "to examine" too...what do you think about it? Do you think they both can go?
I checked them in the dictionary and it says they both could mean "to examine".

Thank you very much.

Do they have to be phrasal verbs? I was thinking just "read" or "read through" maybe "review."

Either "go over" or "look over" would work.

They should be phrasal verbs...but the question is this: do they both mean "examine"? does a native speaker use them in every context when he/she wants to mean "examine"? Can they always replace "examine" in every context?

"Look over" seems more cursory to me than "go over" but it would be a bad test question if one were marked right and one were marked wrong.

"Look over" feels more like a quick review, while "go over" feels more intense.
