Importance of sterochemistry and Fisher projections on MCAT

Members don't see this ad.

i'd appreciate it if anyone can give some comments feedback on how important this is for the mcat. It seems like most / all MCATS have some question on this topic and it's fairly prevalent..

And worthwhile to study/nail it down..?

its important if it shows up on your mcat

and since you dont know that i would study anything that has shown up on the AAMC exams, SA's, or content outlines.

Fisher projections isn't listed as a topic under AAMC subject list.

It showed up in one of the SAs so it's fair game.

If it's a weakness, work on it. If you can't picture them in your head, try getting a model to get you going. That can help build your mental image so you don't have to rely on them later on.

In a Fischer projection is the left or right substituent sticking out of the plane? And which is dashed back?

Think of it as a bow tie. The left and right substituents are on a wedge, and the top and bottom substituents are on a dash. Draw it and you will see the bow tie.

👍

Also this is pretty fundamental material in organic.

Study it. It has shown up on the test before.

Great guys. Thanks so much.

I got into a rut after my first AAMC # 3 with a 29. I took in on July 26 and since I still had 1/2 of the SN3D material to go, I decided to postpone my Sept 11 test.

Although the postpose test eased my stress levels so I can focus even more on the material, I had a 3 week period of sluggish/unproductive time following july 16. Now at the beginning and really hoping to learn this material, learn from the 1/2 remaining sN2ED, and refreshers until end of October. In November-Dec I'LL Do SA's, and lots of practice tests to prep for early jan MCAT.

It would be great for me some kind words of encouragement or support that you validate my decision. I'm hoping to hit 32-34 and eventually- 36s on my AAMCs. I wanted to see that score on atleast a few AAMCs before I would take the MCAT. A month from August to Sept 11th wasn't enough time for me to finish sn2ed, and take and throughly review the AAMCs.

Now I have to worry about the VR passages too. i loved taking VR every day but I wonder now if I can do that with TPHR and EK 1001 without running out. I guess I can do VR 3 days of the week and review the rest of the days + break until Oct31st. That ought to work well.

Definitely study stereocenters and fisher projections.. the questions are fairly easy and show up in some form or another on almost all exams.

THANKS SO MUCH! THAT'S What i thought 😀

the molecular models are helping a lot. I didn't use one as a freshman taking orgo 7 years ago and using them now make a lot of sense. It's tedious, surely painful at times but the reward (and overcoming this weakness is huge).
