If you are coming into BLA and PSYC 1000 is your first choice for the 'one of' requirements list for BLA in first semester, refer to the PSYC website here [1] for information about sections and when restrictions will be adjusted and lifted for various programs.
I recommend registering in another course from the list while you wait, just in case you don't get into PSYC 1000 when restrictions lift.
