Anonymous participant Yes, approval can depend also on who gets your application. I think there maybe some confusion over your paperwork. I would keep things real simple next time just, just put total monthly income not need to break it down to overtime accommodation etc they can see the deposit on bank statements.
The approval time is reset when they receive the docs they requested. It can take another 10-15 business days, could be earlier.. it is a good sign you have not heard back yet but rejection or cancellation can happen anytime.
What you described profile page, student profile etc can be used in the portfolio. You can find posts by similar applicants who did the same and got approved.
