Lab - $group and Accumulators

Hi… I am using following db for this particular lab. But I am getting results which are not there in the options…

Is there any other conditions I need to take care apart from matching the regex for atleast one oscar and using group stage for calculating avg, max, min and stdDevSamp

mongo mongodb://,, --authenticationDatabase admin --ssl -u m121 -p aggregations --norc
