      @@rias554 okay well yeah you can learn this in a 10th grade class, but you probably go through the content way slower than what happens in college. for example you might do only ionic and covalent bonding for like 1 or 2 days but in a college class we go through a whole chapter in 1 day . for example , Chapter 25 (BONDING RELATIONSHIPS):
      Ionic vs. covalent bonding
      Lattice enthalpy
      Bond length
      Electronegativity
      Polar covalent bonds
      Ionic character of bonds
      All of these topics are done in 1 day

      I'm sure you've moved on from high school now.. but I wanted to come in here and say that math also fascinates me. My teachers somewhat failed to make it interesting and so I've always had the mentality that its "just not for me" or "im not good at it".. but it's so eye opening to see how much I enjoy math and science when I'm actually taught well and understand it.

    this is my alternative in learning right now. because of the pandemic, we used modular classes, basically self study with no discussion. today is my 1st day of class, all we did the whole day is scrambling around the net to look for answers and pass it barely in time. after class, i studied right away just to understand the activities and quizzes i took today. it sucks and i want to drop out right away. #AcademicFreezeNow
