You should be able to do the simple math to figure it out. There are so many different weighting schemes that just reporting weighting is rather useless. You can be sure they’ll do the math themselves.
If weighting is 1 for AP and .5 for honors, assuming 6-8 honors to go with 6 AP, that would mean UW of 3.7-3.75. If that’s accurate you should be in pretty good shape. 3.8 would solidify it.
No, reporting the Subject Test isn’t worth it. And I agree, Naviance without specific majors isn’t very helpful. Students may have been admitted into majors with lower stat cutoffs.
