Forget "if" Decide when.
Treat each chapter as a book in itself. There is no point rushing a chapter of a textbook because you often need to understand the chapter before the next one makes sense.
The experience of activating a chapter can be similar to the 5 day test. Many layers until it gels. Since chapters are generally shorter than books you don't need 5 days. Regular breaks aids memory so activate with a timer and take breaks.
