Angol középszintű nyelvvizsga, fordítás (? )

Nézegettem neten elvileg nyelvvizsgás feladatokat. Megcsináltam egy fordítást, nyelvvizsgán is ilyen egyszerűeket raknak be, vagy ez nem "hiteles"?

Ez lenne az: John is considered to work badly but I don’t think so. If they knew him like me, then they would know that he works slowly because he wants to do everything perfectly. Last time he wrote the same report twice because he wasn’t satisfied with his own work. I don’t think that he works badly, he is just a little slow. His boss said that he had been watching John for a while but he couldn’t decide if he was slow or just lazy.
