Question

why was taplow worried about his remove

Answer 1

Taplow is in the lower fifth standard. He can’t specialise until he
gets his remove all right. ‘Remove’ is a certificate of promotion to
the next class. He is worried about the remove because much
depends on how he performs in the examination.

Answer 2

Taplow was worried about his remove..
it's because he was absent a day as he was ill
and Mr.crocker Harris had punished him at the last day of the school...as he had not done his homework
so,he gets worried as the next day was the result declaration day
and he was sure that Harris would deduct his marks..
