    need some biochem study tips

    So I am in biochemistry right now and have my first exam in two days. A lot of the material is built off of prior orgo and gen chem knowledge, as this first exam is on amino acids, functional groups, pka curves, and hemoglobin/myoglobin saturation curves, however I just bombed my second quiz on...

    C/C- in Organic Chemistry but I can't retake at my school

    On the online admissions pages for most schools, I didn't see a lot of hard cutoffs per subject, but when I looked at the prerequisites for each school through AADSAS, most schools list "Organic Chemistry - 6.0 credits - 2.0 grade" I'm panicking now because I received a C on my first quarter...

    Sulfur's valence electrons in sulfate ion

    My book (Kaplan MCAT Gen Chem pg 27) says that for the sulfur atom in the sulfate ion, sulfur's 3s and 3p subshells can only contain 8 of these 12 electrons; the other 4 electrons have entered the sulfur atom's 3d subshell, which in elemental sulfur is empty. Why did "the other 4 electrons"...

    Tips on Surviving Organic Chem

    I have just finished my second semester of undergrad, hating gen chem all the way. I am more of a memorization person and the number of concepts frustrated me a bit. I'll be taking orgo, along with stats, microbio, genetics, and phys next year (split up over two semesters of course with a few...

    Where did the second 'o' in 'orgo' come from?

    Seriously, this makes no sense to somebody who calls it 'ochem'. Where ever did the second 'o' come from? Did you guys take orgonic omistry? :thinking:

    Chemistry Questions (Do I have to start all over?)

    Hi all, I am currently in my sophmore year of college, and I am finishing the chemistry for my program. However, my program is "advanced" I guess you could say. It is supposed to be done in a year and a half, instead of two years like med schools require. Instead of the classes saying organic...

    MCAT TLC

    Which TLC solvent system (2:1 Hexanes/Ethyl acetate or 4:1 Hexanes/Ethylacetate) will have a higher Rf when analyzing isoamyl acetate? would it be 4:1 because isoamyl acetate is non polar so it would migrate more? @aldol16

    DOES IT MAKE SENSE TO RETAKE A CHEM CLASS

    I got a B- in chem II at my undergrad institute, and now I'm doing a post-bacc. Does it even make sense to retake for a B-, or would adcoms see that I improved and take that into consideration on my app later on (assuming I get an A)? Thanks in advance!

    Do you have to take analytical chem at your school?
