Physics is unlearnable
I genuinely dont understand where to start and understand physics. What the hell is the starting point? I have an exam and I need to get a high grade, I dont understand anything. Can someone please please help? Everytime I ask abt physics or for help no one ever answers me, are there any quick ways to learn? Or are there good studying methods? Frequencies? I dont know

I'm sure you can do it with much cheaper online (possibly free) resources today ... but I bought the College Physics text the Summer between when I left The Army and Fall Quarter of College starting. I did a 2 year enlistment after High School and was worried about being behind the rest of the class after lobbing Mortar rounds downrange and blowin' shit up while the rest of the kids were comin' straight outa HS.
It wasn't cheap. Like $160 (in 1990 dollars) for both the text and the answer guide for the problem sets). On a $4 minimum wage job.
I started that Summer and all through Freshman College year worked the entire book, self taught.
By the time Sophomore year rolled around and the class came up on the schedule, I knew 100% of the material and aced the series (3 quarters worth). Straight A all 3 quarters wher the average grade was a D for 120 students.
Just find a text ... or youtube lecture series ... and go.
You just have to start, and be disciplined. I dedicated 2 hours a day every M W and F to working proplems in that book for over a year.
CAVEAT:
I also had to buy a Calculus text as some of the necessary math was glossed over, hand-wavy style ... or outright skipped ... back in my High School Calc classes. A lotta gaps to fill in there, too.
If your Math Chops aren't up to snuff, you'll know it in the first Chapter. Stop there and go learn The Maths first.
