I tell you, the promotion of Onion College is not as difficult as you think! ! ! Come to think of it, since we are not born with superpowers, don't rush to go through the proper channels, or you will be miserable. The rule of the onion segment experimental field is that as long as it is the same publishing house, the textbook segment will be retained, so what's wrong with your PK junior? The position is still rising, and each PK has three questions, so you must not do it quickly for the sake of winning quickly, so as long as you make a mistake, the risk will be great! ! ! When calculating win or lose, give priority to those who get more answers correctly, and you should get all the answers right (regardless of time, even if it is 200 hours)! Even if the opponent answers all the questions correctly, the position will not drop (this is the special law of onions)! ! ! Even if you don't have the ability to do it all, ok, bring homework to help search! ! ! Anyway, as long as you get 100% correctly, it is absolutely impossible to drop the paragraph. Don't forget that 60% will be promoted! ! ! Isn't it beautiful? ! ? ! ? !
