If you don't know an answer to a question, do you leave it blank so you won't have points taken off for having the wrong answer? How many answers could you get wrong in order to maintain a decent score like around 380 or 340ish? Thanks
You should answer every question regardless if you don't know the answer since you are not penalized for it (like in the SATs :/) but I'm not sure about how many questions you need right, don't remember.
