Simply... incredible!
I am a teacher and I bought the whole series.
Now, 1 book for each subject and I'm sorted!
I was hesitant about the "one book for all subjects" if something like that could be comprehensive and detailed.
That's why I looked for it in a bookstore.
And yet!
It is the most understandable in terms of solutions compared to what is available in the market.
Thank you Lysari!

The most user-friendly and practical solution I have ever purchased! You can easily find the solution to any exercise you are looking for, without needing endless flipping through pages! Fully organized by lesson and with perfect design.

Excellent aid! It contains everything and the answers are comprehensive and understandable! Very good idea to include the solutions on each page of the book. We saved a lot of time!!
