“Never trust a supervisor who is always smiling and does not warn you or criticise you. In my case, supervisors never told me anything about if the thesis was in good shape“. I can confirm the HoD is absolutely right.

That was exactly my experience with my supervisor, which made me got six months of major corrections. Both internal and external examiners emphasised that I articulated well and I understood my thesis. Therefore you passed your viva. However, your thesis still needs some significant changes of six months, according to the chairperson. Looking at those corrections report received I realised, it was the lack of adequate supervision.
