If you get to a question and you have no clue what to choose (and you've already tried to make an educated guess), should you guess?
YES! The SAT doesn't have penalties for wrong answers, so guessing (and potentially guessing correctly), is a risk you should take!
List three data structures, and potential uses for each of them.
1) Queue: a queue is a (FIFO) data structure. Imagine a line. If you were the first person to get in line, then you will be the first person to be served. 2) Array: an array is a kind of list. Think of several people standing in a line shoulder-to-shoulder. You need to know the size of the list beforehand, and it cannot be changed without making a completely new list and copying the old list over. 3) ArrayList: an array list is a more flexible array. Think of an accordion. It is fairly easy to shrink or expand it. An arraylist stretches and contracts to the number of elements within it.
List three different words that are pronounced the same way but have different meanings (homonyms). Tell me the difference between the two words, and give example sentences!
Plane vs. Plain: One is a mode of transportation, the other can either be a field or something without frills / not fancy or outstanding. Jeans vs. Genes: one is an item of clothing, the other are units of heredity that are transferred from parents to offspring. Their vs There: one is a word used to denote possession, the other is something to describe the placement of something.
