Really good book it seems. Would like to hear your follow-up after you complete the books. Best wishes

I know this isn’t the usual on your channel but please do the pre algebra to algebra to precalculus sequence next precalculus also has proofs one level ahead

You don't sound too impressed. It actually might be quite good if used appropriately. First look over and understand the worked examples. Then put it away for a week and go back to the examples but don't look at the solution; try to work it out yourself. Then compare your solution with his solution to see how you did and to understand any problems. When you learn what you can from that, then go to the next example. Work through all the worked examples that way. When done, then it's time to go on to the actual exercises. Spend a good deal of time working on one: really try to find the solution yourself without looking. It could take 2 or 3 hours. Then look at the hints if needed. Finally check your solution and understand any mistakes. I think you would gain a lot like that. It doesn't look like a book that you would just sit down and crank through in short order, more of a longer effort.
