Is it better to use 'elif' or consecutive 'if' statements alongside return statements?

This question is specifically regarding coding convention. I know that using if or elif in this case will produce the same results. Just wondering which is the "proper" way to construct this function:

With consecutive if:

def can_take(self, selectedCourse):
    if selectedCourse.hasPassed():
        return False
    if selectedCourse.getPrereqs() != 'none':
        for prereq in selectedCourse.getPrereqs():
            if not self.courses[prereq].hasPassed():
                return False

    return True

With elif:

def can_take(self, selectedCourse):
    if selectedCourse.hasPassed():
        return False
    elif selectedCourse.getPrereqs() != 'none':
        for prereq in selectedCourse.getPrereqs():
            if not self.courses[prereq].hasPassed():
                return False

    return True
