At Wittenborg, we have modules which help you develop your English Language competency. These are as follows: 
a) Mandatory PDP (Personal Development Planning) module which includes Academic English, as well as TIPS (Training in Interpersonal Skills) module. These two modules are mandatory for Phase 1 and Phase 2 Bachelor students but optional for Master students. These modules help you to develop your academic writing skills as well as presentation skills. You will have opportunities to practice these skills by participating in the lessons, activities and seminars.
b) For students who failed the Support English Assessment (the Diagnostic Writing Test carried out during Introduction Day), they have to attend the Support English module. This support module will help to raise your English standards to a level where the general English is solid enough to eventually incorporate the more specific skills of Academic English.

Apart from the above, you can also do your own self-study through relevant reading materials or referring to English/Grammar/Vocabulary online sources. Try the following:
i) Check the EEG Part 5a Academic Writing Handbook for guides on the language and how to do referencing 

ii) Read this News article which gives suggestions on how you can improve your English

iii) Visit the website BBC: Go the Distance: Academic Writing

iv) Visit the website Harvard College Writing Centre: Strategies for Essay Writing

If you need further help, contact your English teacher or your process tutor/study advisor.
