Let us go back to what you already have; your driver’s manual. This is the one thing you got and this is for free provided by the local DMV. This contains all the information that you need for you to get at least the 85% passing rate. The problem is that people have a different way of being able to learn the essential details for the test. This is why after taking all the things that you can absorb from the driver’s manual, feel free to explore other possibilities for reference.
It would be best to start the search online.
Other manuals
I am not saying that the manual that you got from the DMV is not effective. I am saying that this is not really for everyone. Some publishers had gone ahead and made an effort to redo the whole layout of the manual in order to have it easier to digest. This can be partitioned in such a way you can take it one portion at a time to have it lesser overwhelming.
Practice Tests
You will not be able to determine if you are able to get yourself tested on the things you have read or reviewed on. You can take on some fee practice tests that are available online. You can then take on some paid practice tests where you can really test what you have learned so far. You can visit this link if you prefer to take it into action http://www.dmv.com/practice-tests
This is going to take out the surprise in the actual test. Some practice tests that you may find online even claims that they use some questions from the old tests.
This should give you an idea on really how to prepare for the written exam. This is not something that you ought to take lightly. It is going to have you seriously regret for something that you could have prepared for in the first place.
