You study the little pamphlet then walk in and take a short written test. That gets you your temps then you can take the class. The test is not hard.
Get signed up for the class right away, they fill up fast. Good choice taking the class. Be sure you follow the MSF rules they have zero tolerance on those. On time and the required gear
On the temps you can ride, helmet is mandatory, no highway and no passengers.
Link to pamphlet for the test.
