I only solved the questions from 2022, and I've erased my writing. Please be aware that there may be some remaining marks. This book contains past exam questions for both the first and second semesters, covering four years' worth. This is the latest 2024 edition. The list price is high, so I think this is a great deal. I also have other reference books available, so bulk purchases are welcome. Feel free to comment. Please purchase only if you understand that this item has been stored by a private individual.
