n1/n2 should be n2/n1

There is a typo in the 2010 Edition of the GS text (oddly, all 15 previous editions had it correct but the transfer to color, somehow it happened).

Here you can confirm the way it should be written: http://theory.uwinnipeg.ca/physics/light/node5.html

BIO-07

The section dealing with endo/exocytosis; it appears that endocytosis is repeated twice leaving out the explanation of exocytosis. Would it be possible to supply us with the real passage.

Thanks

Hello, yes this is a typo in the book, but for the new edition it will be corrected. Here is the passage:

Exocytosis, is essentially the reverse process. T he cell directs an intracellular vesicle to fuse with the plasma membrane thus releasing its contents to the exterior (i.e. neurotransmitters, pancreatic enzymes, etc).

Good luck with your studies!

"Exocytosis, is essentially the reverse process. T he cell directs an intracellular vesicle to fuse with the plasma membrane thus releasing its contents to the exterior (i.e. neurotransmitters, pancreatic enzymes, etc)."

Is this the passage that was supposed to be included in the book? It seems like you have explained it in the simplest terms but it would be nice to have the passage that was supposed to be in the book.

This is the excerpt from the previous book, but because of a printing error was not added. The next edition will have this mistake corrected. But yes, this is what the Gold Standard states about exocytosis.

Keep in mind the following: the MCAT is unlike any undergrad exam you will ever take. It is not trying to test you on details of mechanisms or your ability to memorize long lists of facts or data. On the one hand, you must master the basics but the focus of the exam with be your ability to problem solve. You will understand what this means as you do the chapter review questions, GS practice tests, AAMC practice tests and problems from the Official MCAT Guide published by the AAMC: Official MCAT Guide

Typos were corrected in the 2011 Edition that was released about 2 months ago but for those of you who have the 2010 Edition, I went through it to see if there was any meaning or content issues that could affect your interpretation of information. So the next posts are the result. This is for Gen Chem.

CHM-37 cm3 should be cm^3

CHM-60 this should seem obvious but just in case: you will see "10-10" in the first column and it should be "10^-10" (ie 10 to the power of -10); and you will see in the second column: log100 = log 1; the 100 is 10^0

CHM-96 N2O4: the 2 and 4 are subscripts

CHM-100 ZnSO4: the 4 is a subscript

Physics

By the way, don't forget we made a summary page with everything you need to know: www.goldstandard-mcat.com/physics-equation-lists/

PHY-04 figure III.B.1.1 the resultant vector (dashed line) is labeled a but it should be labelled either r OR a + b as both are correct.

PHY-06 trig table: the tan column had math symbols converted to numbers. Here are the typos in that column: (1) tan theta NOT tan 2; (2) 1 over root 3; (2) root 3; (4) the "4" in the column should be the infinity symbol. PLEASE NOTE: nothing in these columns are to be memorized. For the MCAT, that information must be derived from the information in the text or first principles (ie standard triangles).

PHY-15: last line in the left column: the "up" should be subscript.

PHY-17: the ft/ should be ft/s (left column)

PHY-21 this one is obvious: there is a letter k in an equation in the right column that should be a subscript.

PHY-61 (a) division sign was correct in the general equation but missing in the following: (Inew/Iold) (b) in the calculation, the number 7 is a superscript not subscript.

PHY-91 snell's law described above (correct in the Formula list link above).

Biology (again, corrected in 2011 Ed.)

BIO-07 Exocytosis paragraph explained above

BIO-69 First column "whcrete" should be: which secrete

BIO-99 last line, right column: "unctional" should be: functional

[mcat_premed3832]

And finally . . . Organic!

ORG-89: bottom of left column: above the word "Acidic" you will see an "H" impossibly by itself: it should be "CH"; and this next issue is really just an esthetic issue that was improved in the new edition: the Neutral and Basic forms would be better at the bottom of the right column so the equation is continuous making it easier to remember.

ORG-104: second column: "as described above" should be: as described previously
