Thank you for viewing. I am selling a book to prepare for web tests. It also covers C-GAB. I studied by selecting and working through the corresponding problems in this reference book and successfully achieved good results on the test recently. It's a highly recommended book. There are no markings, but the pages that were opened tend to stay open easily. - Title: The Most Comprehensive! Web Test Tamatebako - Author: Naoko Kunigami - Published: December 2024 - Price: 1,430 yen - ISBN: 978-4-7141-4108-1 Thank you.
