Sutton Coldfield to Queen Mary's girls School advice please

[Secondtimeround]

As name suggests this is my second time of using this great forum, last time was for DS and he's in year 11 now so been a while. Now starting journey with dd, be taking the exam 2018 currently in yr 5. I just wondered if the bus scenario had improved from Sutton to the school? can anyone advise on any green bus or ones that go from Sutton, routes, or anyone doing the journey at the moment? Any advice at all would be much appreciated. We visited the open morning today and my dd really liked the school. Thank you
