After walking through the hallway for a brief moment, Thorax has guided Twilight to the classroom where they will have their mathematics class, and the room they will be attending is room B07, the bruise on Twilight's left cheek is also beginning to heal a bit. Once Thorax reached the door of the classroom, he stepped aside to allow Twilight to enter.

"Mares first." Thorax said in a loyal tone that made Twilight blush.

"Oh my, such a kind gentlecolt or changeling." Twilight thought. But, she shook her head and snapped out of her thoughts "Thank you Thorax." She said with a smile, and he returned the gesture with a nod.

Then, Twilight entered the classroom and Thorax entered after her.

Twilight scrutinized the classroom for a bit and noticed that it was a bit larger compared to the others.

"Take a seat please." The stallion teacher told her.

Twilight nodded and began to find a seat. Many at the back were taken as well as the middle row. But, there were two empty chairs and tables at the front row, and the table were stationed next to each other.

"I guess I'm sitting there then." Twilight said.

Then, she walked up to one of the empty seat and table on the front row. Once she got to it, she first placed her backpack next to the table. After that, she pulled the chair back and sat on it. Finally, she activated her horn and pulled out her mathematics book as well as her pencil case and placed it on the table.

"What a coincidence."

Twilight looked to the source of the voice and saw the changeling Thorax taking a seat next to her with his book and pencil case on the table.

"It sure is." Twilight said with a giggle. Then, the lesson started.

"Alright class, today we're going to learn about area and perimeter." The teacher told them "Can anyone here tell me what an area is?" He asked them.

There was a brief moment of silence, then, the changeling Thorax raised his right hoof.

"Yes Thorax?"

"An area is basically how much space is occupied in a flat shape or a surface of an object." Thorax replied.

"Very good." The teacher said with a smile "Can anyone tell me the area of a rectangle?" He asked the class. After a brief moment, Twilight Sparkle raised her hoof.

"Yes Twilight Sparkle?"

"Is it length times width?"

"Correct." The teacher said with a smile "So you see class, the area of a figure is the number of unit squares that cover the surface of a closed figure. They are measured in square units known as: square centimetres, square feet, square metres, square inches etc." He delineated to them, and the students were intrigued by the information.

"Okay moving on." The teacher said "Can anyone tell me what a perimeter is?" He asked the class. Ten seconds later, Twilight Sparkle raised her hoof again.

"Yes?"

"The perimeter is the uh... uh..."

Twilight has forgotten what the perimeter of a shape is again, she sucked at this maths topic due to it being very perplexing. The amount of silence in the room made two mares at the back of the room snicker.

"What an idiot." Starlight whispered to Trixie.

"Indeed." Trixie whispered back.

"Uh... it's uh..." Twilight continued with an anxious expression. Then, Thorax decided to help her answer.

"Perimeter is the distance around the edge of a shape sir." Thorax told him "And unlike the area of a shape, perimeter focuses on the outside of a boundary of a shape." He delineated. And the whole class including Twilight were astonished by his answer.

"That is correct." The teacher said with a satisfied expression "You can sit down now Twilight Sparkle." He told her, and Twilight sat down letting out a relieved sigh in the process.

"Yes like what Thorax had said, the perimeter and an area have differences. An area is where you find out how much occupied space there is in a shape, while the perimeter is the calculation of the distance outside of the shape." The teacher told them.

The students were beginning to remember these information that the teacher explained to them, these information would be very significant to them in future exams.

"Alright class, today we need to do surface area so, turn your books to page one-hundred please."

The class did what the teacher told them to do and flipped the pages of their books until it was on page one-hundred. Once they were on the page where is says 'surface area', the teacher came in and gave practice papers based on surface area to the whole class, and the papers had eight questions on them. After going around the class in a circle, the teacher was finished handing them out.

"Okay class, today I need you all to do surface area on these practice sheets." The teacher told them "These practice sheet would be very dandy to you all before exams." He said.

Twilight was staring at the practice sheet with wide eyes due to many of the questions being very complex.

"Anyways, without further ado, all of you may commence."

The whole class then pulled out pencils and erasers from their pencil cases and boxes. After that, they began to do the questions on the practice sheet. Many of the students were having a feasible time doing the questions due to them having learned surface area last week from their teacher.

However, for Twilight Sparkle, she was staring at the sheet with a bewildered expression while holding her pencil with it's tip near one of the questions.

"How do I do this?"

Thorax was doing the surface area questions in a very quick but patient manner because, he is adroit with these questions, plus mathematics is one of his strongest subjects. He is currently on question five now.

"Alright, just three more to go." Thorax thought with a smile.

But before he could move on to the next question, he heard some whimpering noises next to him. Thorax turned his head to his left and saw Twilight Sparkle staring at the questions with a perplexed expression, and he also noticed that she is sweating a little. He must assume that she must be struggling with the questions.

"I should lend her a hoof." He told himself quietly "Hey Twilight." He called her.

"H-huh?" Twilight said snapping out of her thoughts. She turned to her right and saw Thorax looking at her "Oh uh... yes Thorax?" She asked.

"You look like you're struggling." Thorax told her, and she replied with a slow nod "Do you need some help?" He asked her in a polite tone.

"I would love to have some help." Twilight replied with a nod.

"Okay." Thorax said, then he began to teach her "So what shapes do you think an unfolded cylinder has?" He asked her.

Twilight took a while to think about this question, a cylinder is just three circles together. But, an unfolded cylinder is different and it has two circles and one rectangle.

"Oh a cylinder has two circles and one rectangle." Twilight replied.

"Very good." Thorax said with a smile "So in order to find the surface area of a shape, you have to multiply the areas of the flat surfaces of the shapes you see then add them up together. So like you said, a cylinder has two circles and a rectangle. Now, all you need to do is to know their areas and the circumference. So, what is the area of a circle?" He asked her.

"The area of a circle is pi times radius to the power of two."

"And what's the area of the rectangle?"

"Length times width."

"Correct, but remember, this here is a circle." Thorax to her pointing at the curved area of the cylinder "And we need to find the circumference of it, and the circumference of a circle is two times pi times radius. But again, this is a rectangle so, what do we do?" He asked her.

Twilight then began to think carefully about this question. After a brief second, she came up with the answer.

"Two times pi, times radius times height?"

"Correct." Thorax said with a smile "You're a quick learner." He commented, and Twilight blushed slightly from his remark.

"Why thank you." Twilight said in a shy tone "And thank you for helping me with this topic, I now understand what to do." She told him.

"You're welcome Twilight."

Twilight and Thorax then proceeded to do the questions on their sheets with ease due to Twilight now knowing how to do the questions, and Thorax already knowing what to do, and they were doing as quickly as possible before time runs out.

Ten minutes later

Ten minutes later, the timer on the chalkboard rang and the maths teacher told everyone to put down their pencils which they did. After that, the teacher went around the room and began to collect their practice papers. When the teacher collected Twilight's, she was feeling a bit edgy.

"Hey don't stress Twilight, I know you did well."

"I guess, and again thank you so much for teaching me. I appreciate it a lot." Twilight said with a smile towards him.

"You're very welcome." Thorax said with a nod "I'm always delighted to help anyone in need." He told her.

Twilight was blown away by the amount of kindness the changeling is currently giving to her. Her cheeks flushed slightly and she began to stare at Thorax with glittering eyes.

After maths, the last lesson that Twilight has is cooking, and surprisingly, Thorax also attends the cooking lesson as well.

Once they got to the cooking classroom, the teacher assigned the students to make mango juices. The teachers arranged the students in groups of two, and all of them began to grab utensils and ingredients for the obligation. After two minutes, the students managed to grab all of the equipments and ingredients.

Twilight was seen chopping a mango into two slices, now she is trying to cut th inside of the mango out with the fruit knife, and again, she is working with Thorax.

"Come on." Twilight said trying to cut the mango.

Thorax was seen plugging the power plug of the blender in a power socket in order to ready it. Once he has plugged it in, he flipped the power switch and the blender was ready.

"Alright, now all that's left is the mango." Thorax told himself. He turned to see how Twilight was holding up with the mango, and his eyes immediately widened in fear from what he is seeing.

Twilight was was trying to trim the slice of mango with the knife while placing it on the cutting board. And she is facing the knife against herself while trimming it roughly with not patience.

"Whoa! Whoa! Twilight!" Thorax called her.

Twilight immediately ceased her process of trimming out the mango slice when she heard Thorax calling her.

"Yes Thorax?"

"Twilight, the way your trimming the mango is very hazardous." Thorax told her "You could stab yourself with the knife." He finished.

Twilight then came to a realization of her temerarious mistake that could've gotten her maimed.

"Oh right! Sorry."

"It alright, here, let me show you how it's done."

Twilight nodded and placed the mango and fruit knife back on the chopping board. After that, Thorax brought the chopping board in front of him and levitated the knife up with his magic. Then, he began to slowly trim the mango clockwise while facing the cutting edge of the knife away from him, and Twilight was astonished by his skills in connection with cooking. After a brief moment, Thorax pulled the knife out of the mango and placed it on the chopping board. Finally, he flipped over the mango and a slice of mango was now on the chopping board.

"Wow, Thorax, you sure have skills." Twilight said with an impressed expression "And thank you for saving me from peril back there." She told him with an appreciative smile

"Thank you Twilight. And you're welcome, you could've been maimed."

"Your statement is veracious." Twilight agreed with a nod "Anyways, how are you so good at all of these medical based things?" She asked him.

"Oh well, I took up to science and medical when I was a young drone because, when I grow up, I want to be a paramedic." Thorax told her.

Twilight was truly flabbergasted by his statement, she didn't know that Thorax was interested in these subjects. And being a member of the Ponyville Ambulance Service must be a lot of hard work and is a very great goal that he is trying to achieve.

"Wow, now that is a astonishing."

"Indeed Twilight, being a paramedic has been my dream since I was about five years old." Thorax told her, and Twilight was once again very amazed.

Twenty minutes later, the whole class have finished with making their mango juices. They poured them in plastic cups and began drank them in the process, and they were very sweet!

After a while, the school bell rang again and it was time for the students to return home. So, they all bid each other farewell and exited the classroom and began to head to the school gates.

"Well I'll see you tomorrow Twilight."

"See you tomorrow Thorax."

After that, Thorax turned around and began to make his way to the school gates. During that, Twilight was staring at him with a lovely expression towards him, her cheeks were red as well.

"Thorax is such a sweetheart."
