Hi Dina:

My notes and the .SCE exercises I did in SIVP and IPD are all there in the
Google Document folder. I would'nt like to attached them here it will be
unnecessary for others, so I sent out to your yahoo email the access to it
but don't exactly know if that can work - I suggest you create a gmail
account too.

Regards,
Berns B.
