However, some of the less bright ones will still fail in the end, so there's nothing that can be done but make the retake exam even easier.
However, failing a course is failing a course. Even if you pass the make-up exam, it will still leave a record in the academic affairs system, affecting scholarship evaluation and GPA.
In this case, the participation grade, which is part of the final grade, is very important to the overall grade.
E was determined to get as much as possible.
"Okay, student."
Chi Yuan randomly called on a student who raised their hand, then turned around and couldn't help but remind them.
"Hey you guys over there, don't fall asleep, listen carefully, what if this is on the final exam?"
He turned his head back, signaling to the student who had stood up that they could speak up and answer.
"Come on, tell me."
"Since A is an n-order symmetric matrix, let λ be the eigenvalue of A and X be the corresponding eigenvector, then AX = λX..."
"Since A squared = A, we have A squared X = A, that is, A(AX) = A(λX) = λAX = λ squared X..."
"Finally, since X is a non-zero vector, the square of λ - λ = 0, that is, λ(λ-1) = 0. So we get λ = 1 or λ = 1. Therefore, the eigenvalues of A can only be 0 or 1."
"Absolutely correct, add 10 points for participation."
Chi Yuan smiled with satisfaction; he was always very generous with his bonus points.
"This is a fairly common proof problem in linear algebra. Is there anyone else who didn't understand? If not, let's move on to the next question."
After looking around and seeing that no one had raised their hand, Chi Yuan began explaining the next question.
Two hours later, the class finally ended, and the students walked out of the classroom like zombies whose life force had been drained.
After answering some questions from eager students and helping them overcome their learning difficulties, Professor Chi left the teaching building with a thick textbook.
I open my phone, tap on the mini-program, and want to order a cup of coffee.
He still needs to prepare his lessons later, so he'll have an iced Americano to perk himself up, otherwise he'll fall asleep.
To be honest, he didn't even know if coffee would help someone with his condition.
But he felt that it would give him psychological comfort, and that was enough.
"Hey, when did a new coffee shop open at our school?"
As I swipe my thumb across the screen, a brand new store name appears on the food delivery app.
"Why don't we give it a try? We don't know if we'll make a mistake."
Chi Yuan pursed his lips. He had already tried all the coffee shops in the school and university town, and they all tasted pretty much the same.
Occasionally he would discover some truly amazing drinks, but he kept drinking them until he got tired of them.
Hopefully, this coffee shop will bring him some surprises.
With a spirit of courage and a willingness to try, he was just about to place an order when he noticed that the coffee shop's address was quite close to him, on his way back to the office.
Forget it, I'll just walk there. I'm too lazy to order takeout.
The scorching sun hung high overhead, and even walking on the street with an umbrella, you still felt hot, and a few beads of sweat appeared on the tip of your nose.
Pushing open the coffee shop door, the cool air from the air conditioner, carrying the strong aroma of coffee beans, immediately hit him, and the refreshing environment made Chi Yuan feel reborn.
Meow~ Meow~
As soon as he closed the door, a chubby British Shorthair ran over, circling around his legs and affectionately nuzzling his tail.
"Oh dear!"
Chi's dad is here!
The baby sat in the high chair, his excited baby voice echoing throughout the room.
Chi Yuan was also attracted to the baby and couldn't help but look at him many times.
Hello, what would you like to do?
Upon hearing Zai Zai's words, Shen Yulou, who was wiping a coffee cup, immediately looked up and flashed Professor Chi a standard smile that revealed eight clean teeth.
"This is the menu, sir, you can take a look first."
The store manager has such beautiful features, she's a real feast for the eyes.
Chi Yuan sighed inwardly, picked up the cat and moved it aside, then walked over and took the menu from Shen Yulou.
The selection is quite limited, and the prices are low, making it one of the cheaper coffee shops he's been to.
"I'd like a mint iced Americano."
Chi Yuan looked around for a while and then chose a drink that was particularly refreshing.
