This paper discusses about the problems and limitations of the engineering students in gaining achievement and proficiency in language exams and realia. As the students aim at mere passing the subject, they are not able to develop proficiency to communicate in real situations. Due to the academic pressure in their disciplinary studies, engineering students pay little contribution for enhancing linguistic and communication skills. Qualitative ethnography research is conducted to understand the practical difficulties and learning experiences of the students. It is found that the motivation level of the students is low as far as language learning is concerned. The present research implies on the use of cognitive knowledge, discursive techniques and peer interaction in open tasks and suggests how it aids them to display better performances in both achievement and proficiency tests.
