And now that I’ve been through that experience, I want to share some tips with other future test-takers:
1. Study lightly, but well. You don’t have to read the whole DMV manual. The most important chapter is the one on road signs. Then, take practice tests a few days before, and the day of the test. I highly recommend this site.
2. Dress nicely! They will be taking a picture of you, so make sure you look presentable.
3. Bring money. The permit test doesn’t cost anything, but the picture, your future license, and the forms they’ll give you will cost around $80.
4. Relax. It’s only 20 questions, don’t go crazy, you’ll do fine. If you don’t, just study some more and take it again.
Hope that helps!
