No you won't all pass. You have to pass an in-course assessment to decide if you've taken in everything on the course. Your tutors are unlikely to teach you the Laws and should be focussing on game management techniques. You have a responsibility to learn the Laws in your own time. If you don't pass the in-course assessment you won't be allowed to go out and referee your 5 games. You will have to attend the second day of your course again or at least complete the assessment a second time.
You will be expected to demonstrate the correct signals, employ some of the management techniques and to follow the procedures. After that you are sent out to get in your 5 games. Once you complete them you'll be invited back for a law exam. You can fail this exam and will probably be invited back for one re-sit.
You are not a fully qualified referee until you pass the in-course assessment, referee 5 games (minimum) and pass the exam.
Before the change to the course structure around 4 years ago, I had 4 candidates fail or be referred back for more training/an exam re-sit in 5 years. Since the re-structure, I am aware at least 1 falling short every course which equates to around 8 per year. This is because a lot of the emphasis is back on the student to manage their learning and a lot, like in other branches of what I would call non-academic learning, don't get that and expect to have the course learning spoonfed to them.
We have tried to underline the expectations of them and this is reinforced during the course. I think the problem is mainly because the delivery is not like other learning most candidates have experienced before. It's different from school but also the same (yes I know that doesn't make sense). It's not that they don't try, it's just they underestimate the work they have to put in. those that do stick at it after passing are of a high calibre though. So pass, work your socks off and succeed
