Filip attended our school of English language for two years. He had very good results of tests and examinations. He was one of the best from his group. During lessons he willingly took part in discussions. He was especially interested in those about business, finances and marketing. His knowledge showed us that he was really interested in them. He often enquired about matters which interested him. Filip is very ambitious person. He learned by himself additional words to improve his vocabluary level. He repeated at home parts of material which he had problem with. He was punctual and did not miss lessons without serious reason. He was liked by other pupils and was helpful for them. He had strong persistence and consistently pursued the goals. He was independent in many matters, so I am sure his career aspirations are very high. As far as I know he likes playing bilard and is very keen on cycling.

Moja rada staraj się pisać tak, żeby nie wszystkie wyglądały jednakowo.
