The 2013 ARML contest conflicts with
an SAT date. You can arrange a conflict makeup date with SAT,
but it is not a simple matter. It is better if you take the
SAT in May. Information about the alternative
testing
appears here.
ARML is a legitimate conflicting activity, but if you decide you
must take the June SAT, start early working with your school
official to arrange the makeup test. Here
is an official
statement from the College Board stating that ARML
is a legitimate reason for an alternate testing date. You may need
to show this to your school official.
