Advice from Insanity users

I finished my fitness test an hour ago, but the exercise 7 that's like a push-up I couldn't do. I'm terrible at push up as it is, but after the first 6 exercises and this being a harder version of a push up I couldn't do them with good form. In future if I encounter this problem should I do an easier version of the exercise or just keep attempting to do it?
