Just to clarify, when you said you got the grades "written off," what exactly happened? Have you seen a copy of your transcript lately (please order one now just to make sure).
A lot of schools in CA have a program called "academic renewal" which essentially puts an asterisk next to grades and removes them from your GPA. However, the transcript will look something like this:
ENG1 Basic English F* AR
So as you can see, even though in the eyes of that school and all CA schools that grade is no longer factored into your GPA, there is still an F on the transcript that the LSAC will calculate into your GPA.
So you really need to clarify that you got the grades 100% removed or turned into Ws when you assess what kind of LSAT you'll need.
