Hello,

Reading the entire two books, including solving the exercises, in one day will be difficult and moreover you will not be able to understand and study the topics well.

Instead I would suggest you to take time and read each of the chapters, understanding the topics well. While studying the subjects make sure you keep note of important points and equations in a separate book. This will be useful later when you want to revise the subject in one day, as you can then just go through these notes.

Hope this was helpful

Good Luck
