Re: Finding the log of numbers smaller than 1

Thanks for the question! Logs can definitely be tricky and they tend to give students a lot of headaches! I find it easiest to think of logs as "number of zeros" or "number of times the decimal place moves." So, for the example you provided, if we're looking to find the pH of this solution, we can s...

Re: 2000 science Q book: Q 600 (biochemistry)

Isn't the shortest strand (the one that moved the furthest down the gel) represent the 3' end of the complimentary DNA strand, and not the 5'end? Just to directly respond to this, too: the shortest strand will represent the 5' end because that end is synthesized first. So the shortest strands will ...

Re: 2000 science Q book: Q 600 (biochemistry)

It represents the 5' end of the DNA strand that was subjected to the Sanger sequencing. In terms of reading the sequence, we'd start at the bottom (which is the 5' end). It's probably easiest to just memorize that relationship. Here's a video I found useful in visualizing how it's read: https://www....

Re: CARS

There are a lot of passages in the 108 CARS passages book — 12 section tests worth! So, you can likely use the book for both timed and untimed practice. You can also do timed practice on the FLs and the section tests (FL6-10) on the Next Step dashboard. The CARS QBanks on the NS dashboard are also a...

Re: Polarity of Functional Groups AAMC FL2

The science QBook will have some questions like that, so you can dip into that a bit. I'd say the best approach is to be critical in choosing the problems to do and not just blindly do 1-50 or something like that. Instead, skip around, go from question to question, and do those that you think would ...

Re: 2000 science Q book: Q 600 (biochemistry)

Thanks for the question! I've forwarded the typo in answer choice C. I think the confusion may be coming from the fact that DNA is synthesized in 5'-3' direction, but read in the 3'-5' direction? So, the new chains that are terminated the quickest will be nearest the 3' end of the original DNA stran...

Re: NS FL6 B/B #47

Thanks for the question! While the MCAT isn't going to ask you to make clinical diagnoses, they often will ask you to apply your basic knowledge of different systems in the context of disease. That's what's really going on with this question. You can apply your general knowledge of systems to get to...

Re: Science Diagnostic #227

Because it's asking about electronic geometry, we have to consider the locations of the electrons instead of the molecule's atoms. If it asked about molecular geometry, water would be bent, ammonia would be trigonal pyramidal, and methane would be tetrahedral. Since this question specifies electroni...

Re: 2000 science questions: Physics Q 1463-1465

Thanks for the question! While it's true that moment of inertia stuff isn't likely to be tested, it's definitely reasonable to expect that you might have to solve some questions without knowing the exact formulas/expressions, so these sort of problems can still be useful in your prep. These topics a...

Re: NS Physics page 80

These sort of derivations are not going to be super useful on the MCAT, since it's more helpful to be able to recognize trends and patterns than it is to do complicated derivations. Like it says in the book, You don’t have to memorize this derivation for the MCAT, but you should recognize the follow...
