There are two tables to reference - this was in the help docs...
SELECT *
FROM prefix_user AS u
JOIN prefix_user_info_data AS uid ON uid.userid = u.id
JOIN prefix_user_info_field AS uif ON (uid.fieldid = uif.id AND uif.shortname = 'class')
WHERE `deleted` = "1" and `institution`="your school name" and `department` = "your department" and `data` = "class level and number"

I never got the invite but when I logged in via google with correct email, it all seemed to work.

I have not received an invite...
