CARS:
1. look at the answer choices, two are obviously wrong for whatever reason.
Lets say the passage is on the impact of the North Dakota pipeline on the tribes around Fort Yates, ND. The passage talks about the area, the tribal customs, the water supply and general difficulties the tribe faces on a normal basis. The tribe is a mix of Sioux and Cherokee Indians that have come together to form one united tribe back in the days of General Custer. The Tribe lives on land given to them by the administration after General Custer's death and prior to the Mandan Indians being wiped out.
With me?
So let's say the question asks:
Of the tribes that were known to exist in North Dakota during the pipeline development, which one of these does the author state are most LIKELY to impact the non-development of the pipeline?
Answer choices:
1. Mandan Indians
2. Fort Yates Indians
3. General Custer
4. All of the above
Though the passage states all of the first three, the Mandan Indians are long extinct and Custer is dead, therefore, 1 and 3 is out, therefore, 4 is out leaving only 2 as the right answer choice.
That kind of logic in consistent in every section of the MCAT. Two of the answer choices are so obviously wrong for whatever reason leaving two possibilities.
For CARS, my only advice is this:
1. highlight the question type (least like, most likely, MUST BE, cannot be, etc); this alone can help increase points because if you skim this you might miss that little "least" likely and just click the answer choice that answers "likely"
2. quickly figure which two answer choices have nothing, if anything to do with the passage or the author's direction (this should be pretty obvious at the start whether the author is pro the topic, anti or neutral - guarantee that will come up again)
3. make sure your answers that you have left can answer the question... sometimes, the AAMC throws in 2 really wrong answer, with 2 left; one of those being so obtuse that it tricks people into thinking it's right (the old, "OMG, it's so non-understandable it must be right). Don't fall for that trick.
I found with CARS that when I went through the q-packs, I wrote on each and every question why I got it right or wrong; then I summarized my wrong reasons and reviewed them.
I fell for stupid tricks. Fixed them.
Hope this helps a little. Don't give up!
Edited:
At this point, you don't have to void, you can reschedule, I think until tomorrow night.
If you CANNOT reschedule, I would... take the exam, and then decide AT THE END, whether or not to score it.
It is, no doubt, a scary week. It's scary for people are scoring 128s and those who are not. The best advice anyone can give you is be confident.
Seriously.
Go into the exam on whatever date you decide, and be confident. Make it your best friend.
When you decide on an answer, UNLESS it was a LEAST likely that you thought you answered LIKELY on, DO NOT CHANGE the answer choice.
