Crazy question, but where is the chapter on 'Revaluation of an Asset'

Are you asking which chapter in our free course notes?

If you are, then you have presumably read page 2 of the notes and have been watching the lectures.

(If you are not watching the lectures then you should not be using the notes because it is in the lectures that I work through the examples and explain and expand on the notes. They are only lecture notes. If you are not watching the lectures for any reason then you must buy a Study Text from one of the ACCA approved publishers and study from there.)

If you have been watching the lectures, then you will know from my lectures on IAS16 that revaluations are dealt with in my later lectures on limited companies.
