This course helps students to develop and improve their English language skills. It enables them to maintain their progress in English and improve the specific aspects of English in which they are weakest. More precisely, the aims of the course are to build on the vocabulary that the students already know and increase their range of expression. 'Problem areas' of English grammar are revised in order to increase the students' awareness of and sensitivity to degrees of appropriateness in their use of English. Students are encouraged to improve their English outside class by reading widely and practising it with native speakers and with each other. Last but not least, the students are made aware of the fact that they themselves are most responsible for their own progress. The material is organized in units, each of which is based on a different topic and contains a variety of exercises and activities, focussing on the knowledge and skills students require for their English studies. As they work through the material, they progressively revise and, at the same time, build up their level of proficiency.
