40 practice questions written to match the course book of the same level, with 6 of them answered from a spectrum, a trend or a thermal pattern rather than from text. Every answer carries a worked explanation rather than just a letter, because the reasoning is what transfers to the next machine.
These questions were written by Sensemore. They are not an examination paper, are not affiliated with or endorsed by any certification body, and are not taken from any certification body’s question bank. Working through them confers no certification of any kind.
