@Mmparks1 Not sure how he found this out, probably the UK portal or email, but DS texted me on Monday that invitations to merit weekend would be mailed out this week, and the weekends will be 3/9 - 3/10, 3/16 - 3/17, and 3/23 - 3/24.
This is my first rodeo so I have no idea what level of scholarship is required to be invited to merit weekend.
