I think 85-90% is what you should aim for as a minimum. This is the sort of mark that I've heard some airlines look for. This is also certainly achievable with the amount of exam 'help' out there.
And, yes, airlines do indeed look at your school report. They will want to know your progress through both theory and practical training. Not sure about modular to be honest!
