Sure, his spelling could be better but being able to spell well and using grammar isn't as useful as helping someone fix a problem or teaching them something new. he can spell bad and you can still understand him but if someone's bike has broken and they can't ride and he then helps them to fix it and carry on riding i think that is more helpful and will help whoever he helps out in the long run too because they are learning something new.
This takes being anal about spelling and grammar to a new level
