Have to say an oi oi to Cantleave I too took proper exams!!
Unfortunately, despite passing my 'o' levels I did not continue school although I guess I was one of the lucky ones and did attend nursing school at the Royal Free, which was barely acceptable being considered the equivalent of a trade. Despite my JW religous veiws I did want to work for an NGO like medcines sans frontier and do good worldly AND spiritual work.
Fast forward 20 years I went to the Open University, BRITAINS NATIONAL TREASURE , the philosophy module I completed was the best thing I ever did. It fully enabled my critical thinking faculties to flourish & taught me to evaluate claims in a logical way. Without it I would never have fully apreciated ttatt. The sheer arogance of the WT popes to assume that folk that have spent lifetimes studying scriptures, greek, hebrew, Judaic studies etc know nothing and whose work can be brushed aside is astounding. Only after studying a little myself did I fully appreciate this.
Marvster I highly recommend you go for a course there as you do not need GCSE's as a mature student.
