I will start my ATPL distance learning 1 week of next month and I am planning to do with CTC Pro pilot .
Just want to say I searched a lot for good ATPL ground school and top 2 according to me is CTC & BGS.
The reason I am going with CTC pro pilot is because its the closest one from my place. BGS is also good and £150 expensive then CTC, but I would say just look which one is closest to your place as it will save travelling time.
Good Luck
