It has some mistakes, but as a vinyl it has diagrams that are very understandable and focused for the child being examined. However, hygiene is a subject that requires memorization, so I wouldn't recommend that the child study only from there. The exercises are amazing and very accurate!

I bought this particular book because of the detailed diagrams and the wide variety of exercises. The school textbook is simply ridiculous. It is poorly written, with many grammatical errors and densely packed. A student cannot retain information if it is not presented in proper diagrams. And this guidebook solves exactly that problem. However, I rate it with 3 stars purely for subjective reasons. Personally, because I aim for a prestigious school, I am required to memorize the textbook inside out. Here, the guidebook falls short because the theory is not exactly the same as in the school textbook, resulting in, as shown in the image, the need for several changes in the content. Nevertheless, I believe that this guidebook is very useful for any other student as it is more understandable and explanatory than the textbook and it also has a wide variety of exercises (multiple choice, fill in the blanks, judgment questions, critical thinking exercises, and even crossword puzzles!)

Those of you who are taking the national exams from EPAL, buy it, it's worth 100%. It helps you understand because the book is poorly written
