it depends.
if u are an actuarial major student, u should follow ur cirriculum.
if u are self studying, i suggest u take MLC first.
because MLC is somewhat a combination of P and FM(annuity+prob,etc.)

btw the official website is http://www.soa.org/
then u should click on education->exam->ASA-> the exam u wanna take
