PIP Award Review

Hi, Each time I've applied for PIP, I've had to fill in a huge questioaire and then go for a face to face. This time though, the questionaire is very different. It still has a lot of questions but mostly it says to tell them of any changes in the help I need and how I manage my activities now compared to before. I was put in the support group after the last assessment (though at first I had a letter saying I had been kept in the wrag group then a week later another letter came saying that I I been put in support group) I was wondering if anyone else has had this type of form and why is it so different? Does this mean I don't have to have a face to face? Thanks in advance.
