Read them both....

First Lab - Determining the Concentration of an Unknown Ionic Solution

We will use this lab write-up from Qatar University as a "guide" for our lab tomorrow.  Please read it over.  The things we will change include the chemical we will investigate (potentially) and the method we use to dilute it.  Everything else should be ok.  I would use the write-up to create your own data tables ahead of time.

Added this last minute!

2014 Practice FR

So the same goes for the FR.

I took some old problems and listed 3 whole problems first.

Then I cut out sections of old problems to make the 4 "short" questions.

The last one for #5 asks you to draw a Lewis Structure -

2014 Practice AP EXAM MC

So there are ZERO practice tests other than the one I gave you earlier through email.  Even the newer practice books (i.e. Princeton Review) do not follow the guidelines for what material should/should not be covered.  With the new format sets of questions will reference a graph, chart, table, Lewis Structure, etc.

So, I combed through free response sections, CUT OUT WITH SCISSORS, various charts, tables, etc., and then wrote 60 multiple choice questions.  Though it is not exact to what you will see, it will give you the feel of the exam.  Each page of the linked exam contains a graphic at the top (or bottom if it didn't fit).  The questions for each page refer to the graphic on that page.

Hope it helps.
