The eight questions on the sample 12th grade math test from Smarter Balanced Assessments, which is developing Common Core tests for 31 states:

Extra Credit:

Compare these problems to the sample math problems on the high school math exam given in Finland, and connect this to the ongoing buzz about why Finnish students are outperforming ours.

Extra Credit part 2:

Identify the appropriate grade level for each question.

I'll go first:
1. 4
2. 8
3. 7
4. 8
5. 12
6. 6
7. 7
8. 5

Disclaimer: I am not now, nor have I ever been, a teacher, much less a teacher of mathematics, nor do I have any children in school, but I have completed all of the above grades satisfactorily.

I'm going to stand by my grade-level estimate for problem 5. I just plugged (blank), 0.25, 65, and 3 into this online calculator and it comes up with 62.977 for the height at the 25th percentile. I knew it wasn't going to be a nice number.

I'm finding #4 hard. It looks like it should be 2^x, but that's not what it's actually showing. I see the points: (0,1), (1,2), (2,4), (3, sort-of 7), with the last y-coordinate looking a little bigger than 7, but no where near 8.

That's not 2^x.
