Half of the students that made an A failed the last test and now have a B. What percent of the class now has a B average in math class?

2 assumptions:
1. The table shown is before the last test.
2. Every other student stayed the same on the last test
Then half the students who had an A (4 of those 8 A students) are now added to the 12 who had B's. 16 people have B's now. There are 8+12+5+4+3=32 students in the class. 16/32= 50% now have a B.
If either of my above assumptions is wrong, then my answer is wrong.
