помогите перевести на российский без переводчика My friend Henry is not

Помогите перевести на российский без переводчика My friend Henry is not the best pupil. He likes Science and History and he likes making photos. But he doesnt spend enough time on his favourite subjects. His marks are not good. I think he should study more seriously to get better results. Besides, he should make photos more carefully and neatly because they are not often good, either.
