I graduated form my alma mater in 1977 and I knew all my school records are on computer so I’m sure Obama’s are as well. If any records are on computer on any college campus there will be some net connection somewhere in the network, a hackable connection no matter how secure. Only exception ... they have been removed and that would still leave a footprint somewhere.
The Ivy League schools were some of the slowest to computerize and they’ve had some data losses over the years.
Besides, you’d need to get ahold of the original paper documents to be sure anyway.
