My kids have taken lots of tests at Prometric which they find less stressful than whatever the distance proctored home version of tests will be. The weekends are usually packed with kids, often taking JHU- CTY. She said the test was “fine” last year which means there wasn’t terrible about the experience. She didn’t mention she couldn’t skip sections and wished she could.
My kids always have big jumps between the two tests so I always recommend two sittings.
