I like that instead of the usual browbeating and "you're useless" from instructors and others in most series, the instructors of this guy actually seem to highly respect him and his effort.
Also, anyone else like that goblins seem to be taken seriously in this story? They require a high ranking adventurer to accompany a party to go kill goblins, implying that they're not dismissed or treated as a joke. Which makes sense, as, though stupid, they are far above the intelligence of a normal monster. A stupid, weak person is still always far more dangerous than something that is stupid and incapable of thinking outside of biting and flailing.
