'Revise' vs 'Revise for'

Hi

Could you please tell me which one of the following sounds more natural to you?

1- He has to revise his Physics exam.
2- He has to revise for his Physics exam.

Hi Tom,

Revise means to look at/consider again. You could revise your opinions on something/revise your outlook/views. Revise for has a special meaning as in your sentence suggesting look over some past notes/material before an exam. So you need the second sentence. This often expressed as: Do some revision for the exam

A

That’s something he should do before turning it in!
