IMX/IMR

 

IMR/IMX scores

When swimmers swim in a meet, they acquire an achieved time standard. The more competitive they become, the more meets they attend, and the more events they swim will earn them nationally ranked scores at USA Swimming. Murrieta Makos encourages our swimmers to swim every event offered for your athletes age group at some point during the season. Here is how events are categorized:
