Core Drupal

How can I see what version of drupal core is included in an OA distribution?
And-
Is there a way to update the drupal core to a later version after updating to the latest OA update?

Thank you.

Hello All,

I plan to conduct a usability study with new users to understand how they get oriented and use Drupal for the very first time. I know some of you had concerns about usability testing being favored toward the new users and not the existing ones. We have studies in mind for them as well :) It is just a matter of time and project management.

Here is a rough rough draft of the study. I would be very much interested in your feedback. Based of the feedback, I will go ahead and create a more robust screener and moderator's guide.
