Hi Fhars,
They are already citizen in UK. how's the process if they if i will be their dependent?
Regarding IELTS,
There are 4 sets of exam.
1. Listening - from its word just listen carefully the questions
2. Reading - hardest part for me. highlight the important words or sentences while reading it so that when you get to the question its easy to find the answers.
3. Writing - start to the 2nd part which harder from the 1st part. make sure you write more than 250 words one the 2nd part and 150 on the 1st part.
4. Speaking - I think this is the easiest part. just answer the question using right words.
