Simple.

TOPICS 10 and 11 largely only exist in the AP course BECAUSE of Net Ionic Equation writing on the exam. TOPIC 12 of course, IS Net Ionic Equation Writing. Since we are looking forward to changes on the 2007 exam, I have re-written ALL of these materials, and during January 2007 I am presenting them to my classes for the first time in their new format. It is NOT until I actually USE the materials in the classroom that I find ALL of the typo’s and minor errors. Of course, this process is compounded by the fact that we are shooting largely in the dark in the wake of the College Board’s apparent reluctance to offer much specimen material for the new format. This means I keep amending my thinking and ideas to second guess the type of equations and questions that may be asked in the new format. At the risk of repeating myself, I have been VERY disappointed in the lack of specimen material, and the way we had to drag it out of the College Board.
