Re: Math

Hi amahmood16, you are correct on both accounts. The quotient rule does indeed incorporate the difference, not the sum, of f'g and fg', and -18x = 3 does simplify to x = -1/6. The PCAT Review and Lesson Books have been recently updated with corrections, although these changes might not be reflected ...

Re: Opinions on this score

You can access your scores with percentile rankings by navigating to the Resources tab and then selecting the resource for which you received this score (for example, Full Length Exam 3, Attempt 1), and that will give you a complete score breakdown. If you have any trouble accessing your scores, ple...

Re: Opinions on this score

Hi Sam_S, that's a good question. First of all, congrats on your composite score! In general, your percentile rankings are better indicators than are your scaled scores, and the reason for this is that a 400 on one PCAT might be one percentile, and a 400 on another PCAT might be a completely differe...

Re: Full Length Exams

Hi hkgill, that's a great question! In general, it's a good idea to take your first full-length PCAT exam at the beginning of your prep so that you have a baseline score to build upon. This will help you diagnose the content areas you already know well and the areas you don't know as well, and it wi...

Re: Questions on the PCAT

Hi simsimjoey, Integration by parts is simply the reverse of the product rule for differentiation, which is covered in Chapter 32. Integration by parts is a low-yield topic that is unlikely to be tested on the PCAT. You can find all the topics that are tested on the PCAT here: http://pcatweb.info/do...

Re: Conjugated vaccines

Hi simsimjoey, great question! This topic is covered in Chapter 9 of the PCAT Review Book, and there is also information about vaccines you can use to reinforce this concept in the Types of Immunity content review video. I think this is an area where one of our awesome PCAT tutors would be really he...

Re: Biochemistry

Your questions show that you're definitely thinking about this at a deep level! Cell signaling is one of the most confusing topics in molecular biology as it's so broad (SO many aspects of cellular biology can contribute to cell signaling) with a lot of moving parts (what's a GPCR? what does cAMP do...

Re: Biochemistry

Hi simsimjoey, The relationship between pKa and pH is described by the Henderson-Hasselbalch equation: pH = pKa + log [base]/[acid]. Specifically, the pKa describes the pH at the half-equivalence point. To determine the charge of histidine or most amino acids at a given pH with complete certainty, y...
