Pearson Math, Topic 3 test. 19 questions, son missed 4 and received a 68. Do these tests have different weights on their answers? He's always gotten 100 up to now so I'm not sure. Confused because his grade should be 10 points higher. The questions he got wrong are not 2 part or any more involved then the ones he got right. Anyone know? I'm not familiar with Pearson, we teach My Math at my school. Trying to get some insight before I send a note in.
