I bought it 1 month ago but haven't opened and read it even once. I already have many suggestion books with me. However, what I understood after reading the book today is that anyone who reads this book can easily pass college or board exams as well as achieve good results. The reason for saying this is that today I checked and compared my college questions and HSC-2026 questions myself. A lot of common questions came from this book. Therefore, contact if anyone is interested in taking the book, otherwise do not disturb unnecessarily.
