I give some part from the text "Life at Mokameh Ghat". The ‘idea’ to establish a school for the children of workmen and of the lowly-paid railway staff at Mokameh Ghat was a great success. It was carried out by renting a hut for twenty odd students, appointing a master who had to tactfully overcome the initial hurdle of caste prejudices. Now my question is what does it mean by the "The idea to establish a school was a great success.? Do the two phrases "was a great success" and "was greatly successful" mean the same thing? Please explain. I am confused.
