      There's this process called "reading" and things called "books".
      While doing the process, comprehension is necessary to understand the things being read. Once stored inside the organ called "brain", you can retrieve the information and apply it when answering exams. Hope this helps!

      2 reasons:
      1- the person who can break down a complex process is simply smarter than the person who makes that complex process exceedingly complex and convoluted.
      2- the person giving the lecture, along with the faculty of a given institution feels the need to justify themselves, their education, and their job by taking a topic that could probably be understood by a middle school student, and removing any context by breaking it up into their constituent parts; consequently, breaking up what should be very clear and concise material, into pieces that we have to, unnecessarily, put back together, ultimately, wasting our time, money, and confidence.
      I suspect the publishers of the books play a role in this as well. After all, it’s much easier to sell books at a premium price, along with often unnecessary revisions, when the material is put together in this convoluted manner.
      It’s all a racket that is sanctioned by the department of education.

    I love your vids. Final year of medschool and wish I had found you sooner. If I need to review something (or in some cases learn fresh!) this is an excellent resource since it covers the basics. Should you feel you need to go more in-depth there's no shortage of resources but simple and clear quality introductions like these are hard to come by.

    Great video! I like how you explain everything simply and with great visual aids. I am trying to inform myself about how allergies work after recently being diagnosed with Alpha-gal Syndrome and this was very helpful. Would you please make a video about exactly how Alpha-gal works and how it ties into everything in this video. Thanks!
