How to use your course

What confident candidates do differently

Questions alone don’t build confidence — the way you practice does. Here’s the approach we recommend.

Step 1Practice chapter by chapter

Work through one chapter set at a time so each topic is solid before you move on.

Step 2Read every explanation

Even when you’re right. Explanations show you why the other options are wrong — that’s what the exam tests.

Step 3Revisit your weak chapters

Retake the sets where you scored lowest. Unlimited attempts make this easy.

Step 4Sit a timed mock exam

Take a full mock under exam conditions. When you score well consistently, you’re ready to book.

🔒Secure checkout

Pay through our store’s standard checkout.

♾️Unlimited attempts

Retake any question set or mock exam as often as you need for 180 days.

Questions

Frequently asked questions

Do I need the Basic course as well as a method course?

If you haven’t passed the Basic exam yet, yes. Level III requires the Basic exam plus at least one method exam, so most candidates prepare for both. If you’ve already passed Basic, you only need your method course.

How long do I have access?

Every course includes 180 days of access from enrollment, with unlimited attempts at every question set and mock exam.

How do I know when I’m ready to book my exam?

Work through every chapter, review the explanations, then sit the full mock exams under timed conditions. Consistently strong mock scores are the best sign you’re ready.

Can I buy more than one course at once?

Yes. Tick “Add to bundle” on each course, then use “Add all to cart” in the bar at the bottom of the screen. Everything goes through a single checkout.

How do I start after paying?

Log in to your student dashboard once your order is confirmed. Your courses are listed there and work on phone, tablet and desktop.

What if something goes wrong with my purchase?

Not sure where to start?

Most candidates begin with the Basic course — it’s required for every Level III method and it’s our highest-rated course.
