⚠️ The LEC problem compilation and the TAC general knowledge multiple-choice questions have a lot of writing in them. They are not recommended for those who want to solve them from scratch. ⚠️ They are recommended for those who want to understand what kind of questions will be asked, want to solve Tokyo Metropolitan Government-style questions other than past questions, or don't mind erasing the writing. Each mock exam costs around 6,000 yen (even just to purchase the questions), so I think it's a very affordable price to get your hands on Tokyo Metropolitan Government-style questions.
