Seneca Learning for the Win.
I have pre-knowledge of Seneca as my wife is a teacher so I was aware of their good work, I was not prepared for just how good the material and test were and just how detailed the assistance was. I had the Premium package which I initially thought to be on the high side but given everything in the package and the support and self-belief it gave my daughter it was worth every penny and I will be re-visiting Seneca when my son gets old enough for his GCSE's as well. Great customer service and an easy-to-use website make this an all-around fantastic website and service to use, Highly Recommend.
