Thank you for viewing. Complete answer collection for the Class 1 Electrical Engineer First Exam, based on 10 years of data. Class 1 Electrical Engineer First Exam Complete Answers Publisher: Ohmsha This is a collection of past questions from the first exam of the Class 1 Electrical Engineer, commonly known as the Denken 1st exam. Past questions from 2009 (Heisei 21) to 2018 (Heisei 30) are included. I bought a lot of past Denken 1st exam questions, but I ended up not using this one, so it's been sitting unused. It's in pristine condition, with no folds or writing, just as it was when I bought it new. There are no pets or smokers in the house. Thank you.
