hello

generally this level is conducted in two parts- writing ability test and personal interview.

to work on your writing skills, you should look at previous question papers and work on them. This will give an idea about the exam pattern. develop the habit of reading national and local news to improve your vocabulary skills. collect information on current affairs as this will help you to update your general awareness.

for the interview part, you could think of answers to common interview questions like "What are your hobbies?", "Why would you like to study this course?", "Tell us something about yourself", etc. practice to speak in front of a mirror and work on your body language, this bit is conducted to check your personality, confidence and your interests.

hope this helps
