Snow- Day! (updated Monday 8PM)

Enjoy your extended weekend snow day!
AP Chem- the AP exam waits for no person! Therefore, we still have work today as we bask by a warm hearth.
I posted a few more released AP questions. Do them within the prescribed time limit and then check your work when the answers are posted. I assume/expect that each student is keeping apace of these problems so that s/he may earn "free points" on upcoming exams when these past topic question types appear.
For copious review: I have posted a massive number of acid/base and acid/base equilibrium text questions (from a different AP Chem text). Do those questions and check your answers against the posted full solutions. I also posted an acid "strength" tutorial and explanations. Use this as part of your study for Thursday's unit exam.
The acid-base unit exam is now on Day 1- Thursday, so the after school, timed practice exam will be given on Tuesday. You will not be given a test unless you can stay for the entire timed test- there are infinitely more practice questions on Blackboard than there are questions on the practice test; you should take the practice test after school if you feel the need for timed test-taking skill practice.
Bio- I do not know for sure but my guess is that the Nervous System unit exam will still be on Thursday, March 5.
I have now posted the Nervous System videos (from class) on Blackboard; review them.
Therefore, the hw objectives are still due on Tuesday. However, objectives 19 through 23 will not be graded because we did not get to them on Friday.
