I have tried everything that I could possibly do and nothing works.
It has been going for many years, I am 22 and feels like I lost a lot of hair due to it.
Am I damned for life?

How do I actually into higher level math? Is grad school the only way? I'm 21, a junior in college and I don't actually understand shit

I couldn't do the exponents section (3 long questions) in my pre calculus paper.

I'm going back to college at 22. We had our mid terms today and I did everything that was covered in the tutorials, but failed when I had to do different variations that we weren't taught. My lecturer told us that we'd get questions similar to the ones we got on tutorials, so I just did the questions in the tutes. We had just enough time to do the questions, and by the time I remembered how to do them (I did easier versions of questions like that in khan academy like 4 months back), I didn't have time. I gave up when I realized I didn't have time and rechecked the other questions. Will probably scrape through with a B.

I'm concerned because I got blindsided on such easy questions. I knew exactly how to solve it half way through the exam but it was too late.

What should I do anons? I know I have to practice more. Can you recommend good precalc books that have difficult questions? What can I do to get better? I can't repeat any subjects because I'm a poorfag. Doing CS.

How was Avagadro’s number discovered? I vaguely remember my chem teacher telling us that it was defined using carbon 12 but how do they know when you have 12.011 grams of carbon you have 6.022x10^23 atoms?

100,000 years is not enough time for any major discrepancy in brain development to occur

Can I digitally reproduce (I mean with Photoshop or similar) impossible colors? https://en.wikipedia.org/wiki/Impossible_color (sorry for wikipedia link)

What happens to physics in 4D? I've seen some interesting claims, like magnesium becoming a noble gas. What do you know of higher dimensional interaction?

Kinda amazing that shitty computers less powerful than a toothbrush can send men to the moon 70 years ago.
