Commended means you are top 50,000 out of 1.5 Million - Congrats!
In Sept. you will know if you move on in the Natl. Merit Competition...
you can probably guess according to your score. Each State has it's own
cutoff ranging from 203 - 223 +. Those that meet that cut off
will move on, the rest are "Commended". There are other threads, 3 or 4,
that detail these cut off point scores for each state. Maybe you can
look under the SAT Forum.
Choose your 2 Colleges carefully, you may qualify for $$ - even if
it's not Natl. Merit Scholar $$.
