ACT tips, tricks, and shortcuts: does anyone know of any? Thanks!?

ok a little trick to this that we found out at our school. ok first of all you don't get points taken from you for wrong answers you need to keep that in mind. you get a point for answering the question you get another one for getting it right (or more or something) but leaving questions blank is a big No No so the trick is when they announce that you have about 5 or 10 minutes left stop what your doing on what ever question your on and go through and fill out the rest of them (you can either choose to go with answering them all C or randomly choose) once you have them all filled out go back to the one you were originally working on and continue to work them out changing the ones you already fill out with the right answer if you know it. By doing this you don't have to worry about leaving questions blank or anything when they say times up. From what I've seen the ones that have done this at my school have gotten higher scores than the ones that didn't. I only found out about it this year -_- wish I had known it sooner.

don't spend all of your time on one question thinking instead first do the questions you know the answer and then come back to the unknown question. so you can have more time to think.

i'm not really good in reading and science but for math i suggest going thru all the problems you know first then go back and answer the ones you didn't know if u have time left over. you don't want to spend more than a minute on any one problem. i don't think u'll need to worry too much about the time restrictions with the english portion.
