Your brain is such a worthless slacker. I’ll prove it.

Relax and stare at this image for a while. After said while (thirty seconds…ish), the colours will begin to disappear (no it’s not a gif). You can even make them go away completely.

What’s happening is called Troxler’s Fading. After a while of receiving the same non-changing information, your brain gets bored and just discards the information because it’s too busy keeping an eye out for more pressing, changing information, like tiger attacks.

You know how when you wear a watch for a while you stop noticing it. Same thing. Your brain is an idiot.

It is pretty though.

The concept of intelligence has some rough backgrounds. 


For example during the 19th century physical anthropologist Samuel George Morton believed that brain size was a measure of intelligence. He measured the sizes of hundreds of human skulls to assert that there was a difference between races.

He concluded that Europeans had the highest brain capacity, followed by Chinese, Southeast Asians, Polynesians, American Indians, and lastly African & Australian Aborigines. 

Ofcourse now we look back at his work and realize it was the result of unconscious bias, reporting selected data, analytical errors & mismeasured skulls. 



IQ tests stand for Intelligence Quotient Test. They are a standardized test that one cannot really study for. An IQ test measures a person’s general intellectual ability to understand ideas compared to the general population at the same developmental level.

How well we reason, distinguish relationships and solve problems and how well we process information, particularly our ability to store and retrieve it are also things IQ tests measure. 

However, IQ tests fail to measure many things such as creativity, emotional sensitivity and social competence. 

IQ tests are fundamentally flawed because they do not take into account the complex nature of the human intellect and its different components. 

Furthermore, IQ tests are not good at predicting how well you are going to do in life. Just because someone scores high, it does not guarantee success. 



Different people are good at different things. Someone might fail at one topic but excel at another. 

As Albert Einstein said, “Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid.”

These are 9 types of intelligence proposed by Howard Gardner. 

  • Naturalist Intelligence (Nature Smart): human sensitivity to the natural word. Have you ever met someone who was really good with animals? Or who had a "green thumb”? Today they can be a chef or a botanist
  • Musical Intelligence (Music Smart): ability to recognize tone, rhythm, timbre, and pitch and more
  • Logical-Mathematical Intelligence (Number/Reasoning Smart) : ability to calculate, quantify, consider propositions and hypotheses, and carry out complete mathematical operations. 
  • Existential Intelligence: sensitivity and capacity to tackle deep questions about human existence, such as the meaning of life, why do we die, and how did we get here.
  • Interpersonal Intelligence (People Smart): ability to understand and interact effectively with others.
  • Bodily-Kinestic Intelligence (Body Smart): manipulate objects and use a variety of physical skills. (athletes, dancers, surgeons)
  • Intrapersonal Intelligence (Self Smart): capacity to understand oneself and one’s thoughts and feelings, and to use such knowledge in planning and directioning one’s life
  • Spatial Intelligence (Picture Smart): those who have an amazing use of mental imagery and artistic skills
  • Linguistic Intelligence (Word Smart): ability to think in words and to use language to express and appreciate complex meanings.

Ofcourse these probably don’t capture everything in the wide range of smarts that we all have.

Introverts & Extroverts Have Different Brains: Which One Are You?

Scientists have discovered that the brains of introverts are actually different from those of extroverts. This isn’t too surprising, especially considering all of the research now coming out of the field of neuroplasticity. It refers to various changes that can take place in the brain (including changes in neural pathways and synapses) as a result of shifts in things like: a person’s behaviour or environment; their perception of the environment around them; neural processes; the way they think and feel and more.

The Greenland shark can live to be 400 years old. Researchers discovered this longevity by carbon dating the sharks’ eyes based on the fallout from nuclear bomb testing in the 1960s, which means there are sharks in the ocean that were born before the United States was a country. Source Source 2

AP Exam Tips


  • Take a ton of practice tests to see what you remember and see what you got wrong
  • Study what you got wrong (look at your notes, crash course videos, online study guides, etc.) (I’m too tired right now to link study materials for you all, sorry, but you can find them, they’re not that hard)
  • Take more practice tests to see if you finally absorbed that information
  • ****take different practice tests just so you don’t get the right answer because the question looked familiar, that helps no one and it just tests how well you remember that specific question, NOT the information
  • If you still got things wrong, study them
  • Take more practice tests
  • Once you’re thinking “oh yeah, I have a good grasp of this,” then go back at some of the questions that you did get right and see if you got them right by chance (like you just randomly picked the right answer and hoped that it was the right one, because chances are, you might not get lucky again on the actual exam)
  • Ways to test to see if you have a good grasp on information:
  • ****try and explain the information to someone (a friend who’s willing (for some reason), a pet, a stuffed animal, etc.) 
    ****weird method I use is a connection map: write down 2 terms, events, etc., then from one of those terms, write down things you can connect to it, explain the connections, and eventually tie it to the second term you put down. This works for exams like history and psych especially. An example (from AP Psych because that’s what I have to study) in which I connect groupthink to PTSD:
  • Groupthink is when we have a tendency to seek concurrence among group members, or form similar attitudes and beliefs based on the whole group. This often leads to people wanting to conform more to the group’s expectations (or what they think those expectations are) so that they are a part of the “in-group.” People often recognize social distance when they are part of an in-group and can distinguish themselves from an out-group, which leads to a whole lotta prejudice, or negative attitude(s) toward and individual based solely on one’s membership in a particular group. Prejudice often leads to violence against another group. Such violence is a major stressor on individuals who are being attacked. If the even is traumatic enough, a person may never really get over the event. A person could develop PTSD, a delayed stress reaction in which an individual involuntarily re-experiences emotional, cognitive, and behavioral aspects of past trauma in the form of flashbacks (common traumas that lead to this include: death, injury, natural disaster, rape, etc.).
  • Practice FRQs because those are more recall than recognition and will help your memory get used to recalling things (just bullet ideas, though, don’t waste your time with paragraphs because:
  •  a) some scorers really don’t care if your paragraphs are the epitome of good writing (e.g. AP Psych), 
  • b) some of them don’t even involve writing (e.g. AP Calculus), 
  • c) content is more important than fluff, and you can worry about your writing style later ) 
  • Study things you still don’t get
  • Take more practice tests
  • Repeat until you make practice tests your master (and eventually FRQs)
  • If you have to speak during your exam, practice speaking. Just get used to it and fine-tune your pronunciation (mainly advice for foreign languages)


  • If you are overextending yourself, stop studying and take a break, you don’t deserve to be so stressed.
  • Remember to eat, drink, etc.
  • Go to bed at a good time 
  • ****use this here thing to calculate when to go to bed based on when you’re supposed to wake up


  • On the morning of the test do whatever you can to make you feel better, even if it means:
  • ****wearing a lucky shirt or any other superstition that might help you
  • ****reminding yourself that this is just a test and that college board is evil
  • ****just saying good things about yourself like “damn I am the best-looking test-taker in this entire room!” or about the situation “hey I get to get out of class to do this!”
  • Because if you feel like you’re gonna do well, you’ll do better than if you think that you’re going to fail. 
  • Read every question because ap tests like to mess with you and give you confusingly worded questions. Do not be fooled, you are better than that.

AND AFTER THE TEST (if you can):

  • Celebrate with a milkshake or whatever (I did that for my AP Euro exam two years ago and it was probably the best decision ever, but you do whatever makes you happy)
  • Take a nap, naps are great (especially if you’re the type of person that gets REALLY tense during the actual exam and gets really tired afterwards no matter how challenging the test was)
  • Just do at least one nice thing for yourself if you can, even if it’s something small like looking at a cat video on youtube


  • Study, try not to overextend yourself as usual, and head to bed earlier
  • ****or calculate when you should go to bed again 
  • Use the same or similar methods depending on the importance and/or ease of the exam (like if one subject is really kicking your ass, study for that one over the one you’re pretty okay with)

Good luck!

For example, we all have a certain amount of neuroticism that can be either subdued or exacerbated by the presence of a stronger trait. If you’re a little neurotic, but extremely open and conscientious, you accept your emotions and handle those anxieties well, so the neuroticism isn’t even noticeable. On the other hand, if you’re only a little neurotic but not at all open or agreeable, your neuroticism is very apparent.

This personality test tells you which of these 5 traits are your strongest.
