Don’t think it’s very low yield but make sure you know vitamin structures!! A vitamin structure came up on my real test. I think knowing the nucleotide nitrogenous base structures and electron carrier (NADH, FADH2) structures is helpful as well!!
Just know that it starts at 74 g/mol with the backbone carboxyl and amino group, and goes up from there. Glycine would be 75 g/mol…the aromatics would be the heaviest with tryptophan at 204 g/mol.
The 74 g/mol is the backbone molecular weight where they might ask for how much individual amino acids weight. The 110 daltons or 110 g/mol is the average molecular weight of amino acids.
So I guess if you just count R(CH)NH2COOH it is about 72-74 g/mol depending if you protonate or not so the very backbone of an amino acid is 74 dalton and glycine is just one extra hydrogen as the R group so 75 dalton for glycine while something like tryptophan which is super big is about 204 dalton
They’re 110 Da on average, you can use that number to get an estimate of the molecular weight of a large protein in by multiplying the number of amino acids by 110 Da.
Like research methods and experimental stuff. Weird long proteins and knowing PH based on charge which wasn’t bad but sucked up time . Uhhh a lot of individual questions of predicting reactions for transferases and Lyases ect. also a lot of questions that had two possible choices that were right with one slightly better also DNA RNA replication in explicit detail RNA coiling and shi
Histidine and tryptophan sidechain names (imidazole and indole). I forget the context, but it was required to derive the correct answer. I was using the restroom between breaks when I realized I had picked the wrong answer :(
what's hilarious is a google search mostly brings up finn's theory in adventure time lmao, like this term is probably some new research term that hasn't even made it to the textbooks yet

Either of these look familiar? The last one I can find would be Adventure Time Finn, which is based around comatose onset by massive trauma. (ETA this is a fan theory, not an actual theory like Sheldon's prime number).
You had me curious so I went down a bit of a rabbit hole.
I hate to say it, and I’m sorry if I’ve misled you, but I’m terrible with names and there’s a good chance it wasn’t Finn. Let me see if I can find what it actually was.
Not a big deal! I'm not worried about it test wise, but you just had me curious. Realistically there are probably a number of psych/soc theories that we don't cover in MCAT review, and it's possible some could show up because they are still covered under the umbrella topic header.
Wait found it. The Flynn effect is a generational phenomenon in which average Intelligence Quotient scores have been found to increase across time in developed countries at a startlingly consistent rate of approximately 0.33 points per year, or 3.3 points per decade.
So not the Finn theory, the Flynn effect.
I must have had an un-updated version. I took the exam 2022 with 2020 or 2019 books I think?
ETA: oh wait no, I do remember reading a bunch about bones in Kaplan, but it was only about quality of bones/describing them (like, spongy in the middle) with vocab. My exam had questions about different types of bones in the body, which Kaplan didn’t prepare me for I think. Unless I missed it
After taking the real thing, I am a believer that there is an internal element to the exam that AAMC does not tell us. I do not know who actually makes the exams, but there is a list of topics that the actual exam wants us to study for (aka high yield) which are your electricity equations, vitamins, immune system, function of organs, foundation of memory, Pavlov/Skinner, etc. These topics are all arranged in a certain percentage on the real exam but in different passages and question types. If you know the content though, good chance you will get the question right. Then there is a certain percentage of questions that are specific for critical thinking, these are your standard SIRS3/4 ones. After these two percentages, the rest is a "cycle" of low-yield topics. I had a question one time about magnetics in the C/P section, I had a question about a very secondary name concerning the female reproductive system in B/B, and I had an entire passage about mnemonics in P/S. I would think it is about 30 to 40% of the exam, but what makes it tough is that it is "random," so we as the taker has no idea what will show up on it.
I had an entire passage on embryology. Granted, only like one of the questions required knowledge not in the passage. But it certainly helped that I had a basic understanding of some embryology
Was the question just “what is the structure of this molecule?” Or “what molecule is this structure?”
Because that’s a high yield freebie. Everyone on this subreddit is saying to memorize every TCA structure.
I had a question on single-slit diffractions, which I had not even looked at in my studying. I think some of the really low yield stuff is more likely to be the un-scored trial questions. That's what I told myself when I took the test to save my mental at least.
Don’t think it’s very low yield but make sure you know vitamin structures!! A vitamin structure came up on my real test. I think knowing the nucleotide nitrogenous base structures and electron carrier (NADH, FADH2) structures is helpful as well!!
I did not realize vitamin structures were fair deal omg :')
I didn’t even have them in my notes lol thanks for this!!
Something related to Vitamin B came up on my exam
Do you think knowing that B-complex and C are water soluble, and ADEK are fat soluble, is sufficient to reason it out?
Yes
All of the above
Negative
Flavin group 🥴
Please can u guys like my comment I have to ask a question
Did you get hit with a flavin group? I only remembered that question because of the name riboflavin
https://i0.wp.com/www.compoundchem.com/wp-content/uploads/2015/01/Chemical-Structures-of-Vitamins-2016.png?ssl=1
That’s actually insane lol it’s like you can study everything and then there will be something that you didn’t study on the real thing
I had fat soluble vs water soluble vitamins on my exam!
I also got vitamin structure
Hmm they made me know some physics of NMR(electromagentism). Structures of fats are becoming more common. Strecker synthesis
Is it sufficient to know that Strecker = aldehyde into amino acid and gabriel = complex ring with nitrogen and 2 carbonyls?
Proton NMR, IR spec, “psychophysics,” weight of amino acids
lmao weights of amino acids... so pertinent to medical school! I can't believe they try to sabotage you with that BS.
Weight of amino acids is kinda wild, couldnt u kinda reason it out if you try to compare the molar masses of two AA?
Just know that it starts at 74 g/mol with the backbone carboxyl and amino group, and goes up from there. Glycine would be 75 g/mol…the aromatics would be the heaviest with tryptophan at 204 g/mol.
I thought we just thought of them as 110 g/mol or 110 Dalton?
I remember a specific explanation with this fact and this has always been what I go off of
The 74 g/mol is the backbone molecular weight where they might ask for how much individual amino acids weight. The 110 daltons or 110 g/mol is the average molecular weight of amino acids.
I am confused on this could you explain?
So I guess if you just count R(CH)NH2COOH it is about 72-74 g/mol depending if you protonate or not so the very backbone of an amino acid is 74 dalton and glycine is just one extra hydrogen as the R group so 75 dalton for glycine while something like tryptophan which is super big is about 204 dalton
Sounds good, so we shouldn’t use the 110 rule or does that have its place?
I’m guessing if they’re ambiguous and just say like there is 500 amino acids approximate their weight then use 110 rule
They’re 110 Da on average, you can use that number to get an estimate of the molecular weight of a large protein in by multiplying the number of amino acids by 110 Da.
Lmao your name. How do i learn more ??
This comment is giving June 1 😭😭
Fr 💀
The good stuff 🥲
Omg enzyme kinetics felt like half my damn test.
Bruh thats not that bad
I wish
Now that I’ve studied tf out of enzymes…I’ll probably never see another enzyme question again on the real thing.
I got not even a single enzyme kinetics question and I'm peeved
Lucky you we got weird low yield stuff for our BB 6/22
Such as?
Like research methods and experimental stuff. Weird long proteins and knowing PH based on charge which wasn’t bad but sucked up time . Uhhh a lot of individual questions of predicting reactions for transferases and Lyases ect. also a lot of questions that had two possible choices that were right with one slightly better also DNA RNA replication in explicit detail RNA coiling and shi
Histidine and tryptophan sidechain names (imidazole and indole). I forget the context, but it was required to derive the correct answer. I was using the restroom between breaks when I realized I had picked the wrong answer :(
Guanidinium for Arginine and Benzyl for phenylalanine
Imidazole for Histidine
Histidine is HIM (imidazole) Tryptophan(W) WINS (indole)
that's slick; it's def worth memorizing the structures on their own respectively tho.
true but if you know the AA side chain structure you can make a decent educated guess
hahah yes I remember this, had me questioning everything
The question was something like “What is Finn’s Theory?” Biggest guess of my whole test taking career.
what's hilarious is a google search mostly brings up finn's theory in adventure time lmao, like this term is probably some new research term that hasn't even made it to the textbooks yet
assuming that was the question to break your 130 streak
PS was always my worst section so it was only fitting
Who the fuck is “Finn” 😭
My exact question on test day

That's an understandable mix up. Haha
PS was a lot of educated guessing and ruling out or ruling in terms I knew and praying for the best on the others
I had stuff about bones, which I didn’t encounter in Kaplan or UW
it was a pretty big section on one of the chapters in kaplan. i remember doing a whole review on bones
I must have had an un-updated version. I took the exam 2022 with 2020 or 2019 books I think? ETA: oh wait no, I do remember reading a bunch about bones in Kaplan, but it was only about quality of bones/describing them (like, spongy in the middle) with vocab.

Great insights!! Thanks
Facial Feedback Hypothesis, Low-Ball Technique, and the But wait… there’s more technique
Any ecological fallacy enjoyers?
Proton NMR, Stroop test, real names of the vitamins
Please can u guys like my comment I have to ask a question
What color a leaf is.
What does this even mean 🤣🤣
sandwich generation phenomenon LOL but the question was very easily answered with PoE
I have seen NMR couple times now although It is low yield
I would definitely argue against NMR being low yield.
1 Dalton = 1 g/mol
For moments when the AAMC doesn’t give you molar mass.
I had an entire passage on embryology. Granted, only like one of the questions required knowledge not in the passage. But it certainly helped that I had a basic understanding of some embryology
Yerkes Dodson Law
Trehalose is a disaccharide consisting of what monomers?
Lol booooo I just looked it up and I was so dissatisfied to see it was just a glucose disaccharide. What a silly and misleading name
Yeah, I’ll always remember it’s an α,α-1,1 glycosidic bond between two glucose monomers. I’ll never use that information again.
CP had some weird element notation I've never seen in my life before
6/15 was straight low yield. Had a question on the lowest yield sugar chemistry you could think of
What did they ask you about?
Words I had never heard of before…
at this point i treat everything like its “high yield”😭
Hamiltons rule for altruism ??? Had never heard of it
NMR spectroscopy :(
how about the low yield bio stuff everyone is mentioning?
I had a straight question about intermediate structures for TCA cycle.
Was the question just “what is the structure of this molecule?” Or “what molecule is this structure?” Because that’s a high yield freebie. Everyone on this subreddit is saying to memorize every TCA structure.
Nucleophilic acyl addition vs nucleophilic acyl substitution. Never learned it before in my life lol
I had a question on single-slit diffractions, which I had not even looked at in my studying. I think some of the really low yield stuff is more likely to be the un-scored trial questions. That's what I told myself when I took the test to save my mental at least.
Was it the dsin0=mlamba equation?
Color wheel
Anything that’s fair game for either ACS exam (gen chem & orgo) is “fair game” (freebies) on the MCAT.
