Before you start

Detailed prerequisites are published with the first lessons.

How to get the most from it

Short, regular sessions work better than one long read.

1. 1
   Go in order

   Each lesson builds on the one before, and later modules refer back to earlier ones.

2. 2
   One module per sitting

   A module is about 20 minutes of reading. Add 10 minutes for the checks and your notes.

3. 3
   Read the Exam focus box first

   It says what the exam expects from that lesson, so you read with a purpose.

4. 4
   Answer before you look

   Commit to an answer in each knowledge check, then read the explanation, even when you were right.

5. 5
   Redraw the diagram

   Every lesson has one diagram that sums it up. If you can sketch it from memory, you have the lesson.

6. 6
   The cases are fictional

   People and companies in the examples are invented, and some of them come back across lessons.

7. 7
   Sign in and come back

   Your place is kept and finished lessons are marked, so short sessions add up.
