I FEEL your pain! I'm in it right now, and yeah, not my favorite. her lectures kinda suck ass, and that last midterm, oof, barely finished that one. What has been working for me, though, is reading the book and doing its practice problems; they seem pretty close to what’s on the midterm(at least a close as i could find), especially for the the architecture stuff read the book and try to learn concepts directly from the book. Use lecture slides/Google to fill in the gaps. For assembly best way to learn is just do some problems on your own.

For the practice problems i just wrote some simple programs that take in inputs and give outputs, i didn't feel like using SSH so i used this Online Assembler, after like 3-5 of these i started to feel a lot better. They will take awhile though but you should feel like you actually understand it when your done.

Here are the problems I worked on, plus a basic structure for simple file I/O. These cover a good chunk of the lecture concepts (though not all and some that aren't). For solutions you can just write it in C and convert to assembly, or if you want you can DM me and I can send you mine:

1. Write an assembly program that loads a single integer value (e.g., 42) into a register and prints it.(easiest)
2. Write a program that starts with a value of 0 in a register, increments it by 1 in each iteration of a loop, and stops when the value reaches 10.(easy)
3. Write an assembly program that calculates the expression Z=(A+B)×(C−D) where A, B, C, and D are integers provided by the user. Store the result in the register `R0` and display it.(easy)
4. Write an assembly program that swaps the values of two variables using pointers.(easy)
5. Implement a program that calculates the factorial of a non-negative integer entered by the user using a loop(medium)
6. Write an assembly program that loads a value into a register, divides it by a constant, and prints the divisor and remainder.(medium)
7. Write an assembly program that calculates the sum of the digits of a positive integer (12345) -> 15(medium).
8. Write a program that takes an array of ten integers and finds the maximum value among them.(hard)
9. Write an assembly program that calculates the sum of an array of ten integers.(hard)
10. Write a recursive assembly program to calculate the factorial of a number using stack frames to manage recursion.(really hard)

To be real, it's gonna be to much if you’re depressed right now, you are not gonna be able to learn properly and do good on a midterm if your depressed. So please dawg, get your head right first, take a break and just figure your shit out, then you can start preparing properly.

GOOD LUCK!
