I bought this last year to prepare for the electrician's skill test. I looked it up online, and it seems that the size of the protective board used in the actual skill test is about this size. I practiced with this after buying it. I can't compare it to the actual protective board used in the test, so I don't know for sure, but it felt a little small? However, some test sites have small desks, so if you can place your tools, materials, and assemble everything within this mat, you should be fine on the actual test day. In my case, the desk on the test day was long, so I could work without worrying too much about the person next to me. I no longer need it, so I'm selling it at a low price. However, I have to add the shipping cost. Shipping is expensive because of the size... I apologize. I will put it in a bag, wrap it in bubble wrap, and ship it in the condition shown in the third picture. As you can see from the condition, there are scratches and stains, so please refrain from purchasing if you are sensitive to such things. Also, no claims and no returns are accepted. This year's published questions were the same as last year's, so if you work hard, you will definitely pass! I'm listing this with a message of encouragement. Thank you.
