Thank you for the questions! How would you recommend that someone who's already done extensive MCAT content review from a comprehensive set of books & questions (Berkeley Review) use the resources available from your course? You have a mental image of the entire conceptual presentation from...

How to Read an MCAT Science Passage When the new MCAT was introduced in 2015, our company became a teaching workshop and development incubator. Our previous course, WikiPremed, had specialized in interdisciplinary methods for the old exam, so we were uniquely poised to help our students with...

Over the years this thread on SDN has functioned as something of a history of WikiPremed. I haven’t been posting so often lately, so I think an update is due. Given WikiPremed’s new found obscurity, a form of re-introduction may be needed. WikiPremed is an open, unified MCAT course that evolved...

This is John Wetzel, creator of the WikiPremed MCAT Course. For the past three years, an important part of development work at WikiPremed has been tutoring students for the new MCAT via Skype. A number of my students are taking the test this month, so I’m posting this ad here at SDN to let folks...

Over the years I have been very thankful for the allowance at SDN for me to post updates about progress at WikiPremed in this thread. This is my first post in a long time. The past couple of years at WikiPremed have been all about teaching for the new exam and rebuilding. We're making progress...

A chemical reaction occurs spontaneously in a certain direction because that direction increases the entropy of the universe. Spontaneity is based on statistical probability. Because the new situation is much more statistically likely, the change is irreversible. How does a chemical reaction...

aldol16 said 'The citrate is only acting as a "shuttle" in the latter. That means that it must be transported back into the mitochondria to replenish your stores of oxaloacetate ' I'm sorry. I'm not really following. By your usage it seems that citrate is a 'shuttle' in either case...

I think and aldol16's comments are very useful, that the branches from succinyl-CoA or alpha-ketoglutarate do not invalidate the idea of citrate synthase as the 'committed step' because the oxaloacetate portion is essentially playing a catalytic role. That's just a very good thing to understand...

Citrate synthase is generally taken to be the committed step. Citrate synthase is extremely exergonic (driven by the thioester substitution) and allosterically regulated, so it has the right properties of the committed step, and there's no major branching pathway between citrate and...

For the past few years I have been tutoring one-on-one students via Skype for the new exam. This teaching has been an essential component of the development of the new WikiPremed. It has been a wonderful experience creatively and very rewarding to help people on an individual level. There are so...
