To add salt to the wound we decided, years later, to relocate our product development company to North Carolina only to discover that, once again, we needed to take a written test to get our license! Amazing. So at the time, we downloaded the darn manual, spend a few hours reading over the book again, went to the DMV, waited and waited, studied some more and then passed the test.
We did what 90% of people probably do, turned to the Internet and searched Google for 'DMV Cheat Sheet California.' What we learned, as you have probably learned, is that nothing existed. When we moved from NY to California we found out that despite having driven for half our natural life and having almost zero tickets to speak of, we needed to take a written test to get our California licenses.
We used to live in California and before that New York.
