hello there!
I had my tse rescoring in November, and thank God I passed! They gave me 50.
you have to fill up the form at the back of the tse bulletin, have your credit card number, and then fax it to the number stated also in that form.
according to them, I do not know if it has changed since the last time I looked at it, it will take three weeks for the new results. it will be mailed to you again. but in my case, it took at least a month and a half. so, during the waiting period, i would suggest that you pray, pray and even pray harder so that the raters will give you the score you want. believe me, that is what I did! praise God!
for the payment scheme, they did not get the $50 payment from me because according to them, if your score has changed, they will not deduct payment from you. but if your score remains the same, then you will pay the amount. this was according to the letter they sent me together with the rescoring score.
i hope this answers your question. Good luck!
