Hi ROny, First of all sorry to hear about your sister.
I know it would be difficult for you and your family, I can understand your view.
Start studing as 65 days are pretty good for group.2, Prepare well, Go slowly and steadily in the begining and then you can keep up the speed as the time plays a key role.
I would like to conclude with this Rony,
Time and Love heals everything.Take care...
