#### Transcript of MCAT 2015

Physics and Math Tips for the MCAT / medical tests
Physics: need to know
Classification: break it down
Questions: 2 types
Units: subtle hint
Math: stick to basics
Examples:
Outline
There is no magic pill or trick that will take the place of studying.
Yet there are some things that can help.

I don't profess to be the expert on MCAT or other medical tests.
Disclaimer

I am from Cache Valley

I dual majored in Physics and Mathematics
(minored in Chemistry)

I began applying for Dental school and took the DAT

Any initial Questions for me?
INTRO.
Richard Datwyler
There is a lot of material
Make a list !!! Check it twice.
Physics: Need to know
AAMC used to have a great list of topics
Principle
Based:
Know the main principles and equations
What type of Problem is this?
Classification
Key phrases
Each type of problem has key phrases
(Kinematics, E&M, Relativity, etc)

Units (know your units this is a good thing)

They will throw misleading info, focus on the primary problem
Things to look for:
How long,
How far,
How fast,
How height,
What is the accerelation, velocity , distance, etc.
Field
Potential
Charge
Electromagnitism
Observer
Relative
'sees'
proper

Passage, and Discrete

Two types of problems
These are the random information question
they do not link up with others, and can be anything.

These should be bread and butter
what you live on.

As you quiz and prepare your self this is what you prep for.

They are the pure fact question
Stand Alone
1. Analyze
What type of problem is this?
(EM, momentum, fluids, etc)
2. Principle that governs this problem
General principle or law
(charges, mass and velocity, non compressible)
Equation
(~kq/r^2 , mv , Av)
3. What are they asking for?
4. DOES IT MAKE SENSE?
What to do?
DO NOT STRESS, DO NOT GIVE UP, FIND THE POINT
Passage
The passage questions are the critical thinking
questions, they test to see if you can understand
what you are reading, interpret the given information and apply general principle
They are NOT impossible
They do a great job of linking ideas!!
1. Scan Passage!
Very Quick overall view of problems common thread
2. Scan questions (you have to click next & prev)
Bit slower scan of questions, this will help you focus on what to look for as you read.
Pay attention to detail regarding question scan
4. Don't give up if topic isn't familiar
The questions might ask completely different fundamental principle
6. Rescan the passage for any needed clarification
you should know where theses are from initial scan and reading
7. Spend a bit more time here
more problems more time.
What to do
Of all the quick tip helps, this is the most important.
UNITS UNITS UNITS
The answer will have a unit!!!
make sure the math gives you the right unit
The question often gives the most probable mistakes for a given question. Thus if you didn't memorize the exact equation you would miss it.
Example Standing wave frequency
if the wavelength is 4 m and the velocity is 20 m/s
what is the fundamental frequency
A. 0.2 Hz
B. 5.0 Hz
C. 0.2 s
D. 5.0 s
It eliminates wrong answer by both
Units given
Math solved
They can solve symbolic problems too.
Learn units of major variables
(mass, momentum, acceleration, force, E&M,etc)
UNITS
No calculator
The good,
ugly
MATH Tips
Having no calculator is alright, it keeps the computation down.
But if you aren't practiced it can be hard
And they will give you the most common mistakes
Order of magnitude
Separate out the power from the number
Move it around
Play with fractions
Top and bottom
Patterns and short cuts
2, 5, 10 quarters are your friends
Sine, cosine (PERCENTS of whole)
30, 45, 60, 90
sin 30 = .5 (think 2)
cos 30 = .866 (10 and 2 / 85 %)

example
37sine 30 (divide by 2 = = 18.5 )
37 cos 30 (think 10 'tithing = 3.7
now think 2 = 1.85
remember steps = = 31.45)
sin 45 = .707 (think 10 and 3 / 70%)
cos 45 = .707

example
23 sine 45 (think 10 = 2.3
times by 3 = 6.9
small steps (16) == 16.1
Take it apart!

2.5 x 10 / ( 5 x 10 )

two parts
NUMBER
2.5 / 5 = .5
POWER
-12 / -15 = + 3

answer .5 x 10 = 500
-12
-15
3
This works for equations as well as answers

1/ L = c/f = = L = f/c

15 / (1/2) = 2 *15 = 30
Take small steps,
if it is times or divide, make the numbers close.
Add and subtract, take whole numbers and then the little bit
Look for nice numbers 2, 10 and branch from there
Examples
1200 x 10 = 1.2 x 10
-15
-12
3700 x 10 = 3.7 x 10
+6
+9
0.0004 x 10 = 4.0 x 10
-7
-11
0.0057 x 10 = 5.7 x 10

QUESTIONS?
Buyer be ware, principle is not always enough
(there are some hint though)
Their list of equations is NOT all inclusive.
Not necessarily for memorization.
Now they have a great work sheet
