Welcome welcome welcome friend!
Thank you for sharing your story. Your honesty and openness will be of help to many other "lurkers".
I relate to your account and circumstances in many ways.
No doubt you have had an in depth look at www.jwfacts.com ? That site has all the key points of a doctrinal nature, all presented with accurate reasoning and scriptural references. Also, it has many personal stories of ones who have woken up. Many were extremely "in" the organization, and "spiritual" witnesses! (One that comes to mind is Stumpy. His account is great!)
Please feel comfortable to share in the discussions here, knowing that it helps not only yourself, but others too. After all, doesn't the bible speak of "an interchange of encouragement"?
PS, you mentioned "tertiary entrance score" Are you from WA by any chance?
