After finding a book and reading it for a while, after Lang had packed up his things, Link and Lang went out together, first walked around the school, became a guide, and had a light meal together in the school cafeteria at noon, and then the two of them went to the place near the school to buy second-hand books.

The price of first-hand books is high, so many people choose to buy second-hand books, and the second-hand bookstores in schools have a relatively complete range of textbooks for the curriculum.

During this time, through conversation, Link learned the basic situation of Lang.

His father is a well-known designer, and his mother also has her own business, which definitely belongs to a wealthy family.

Lang also has two older sisters, he is the youngest child in the family, although today, the concept of patriarchy in the United States has long been diluted, but as the youngest son in the family, Lang still receives more love.

Lang's tuition fees are borne by his family, and he has to pay a lot of living expenses every month, so he has no worries about food and clothing, and there is no pressure in life.

Although Lang did not get a full scholarship like Link, he was able to enter Caltech, and he did not have the slightest problem with his own mind, although he was a little fatter, he was also a top student in middle school.

The school course plan was already arranged when I discussed it with Peggy yesterday, and in the list of physical education elective courses at Caltech, you need to take two physical education courses during the school year and meet the standards.

As for the sports chosen in physical education class, Link's first choice was naturally baseball, and then the second one Link thought about it and chose a three-kilometer run, which requires no practice for Link, and can even be tested directly.

Speaking of which, due to the limited campus area and the small number of students, Cal Poly has a wide range of sports, but even the more popular football, basketball, baseball and other sports do not recruit many talented players.

Caltech's baseball team is just an amateur recreational team with very limited strength.

As the registration day passed, the fall semester officially began, and several courses that Link had selected for this semester also officially began to be taught.

From this time on, Link also began his college life step by step.

I get up at five o'clock every morning to run and exercise, come back to take a shower, clean up breakfast, and then get ready for class.

Caltech's classes generally run from 8 a.m. to 5 p.m., with a two-hour lunch break in between, generally two classes in the morning and two classes in the afternoon, and the duration of each class is about 90 minutes.

The specific class time is arranged on the course selection schedule, and which course you take only needs to go to class on time according to the class schedule.

The curriculum of Cal Poly is generally small, and the number of students in small classes is generally less than 20. Of course, there are also large classes with no limit on the number of students.

Whether students take small class courses or large class courses depends on their own arrangements, anyway, they must get all the credits of the core courses prescribed by the school in the first two academic years before they can enter the learning stage of professional courses.

In the first semester, Link took a total of ten elective courses, with an average of about four classes a day, so it can be said that the classes were full, and most of the rest of the time Link was in the library with Peggy, and he was usually busy until the early hours of the morning in the evening.

When a professor gives a lecture, he does not read it out from the textbook at all, but follows the divergent thinking that is customary in Western-style education, and extends it from the textbook.

To keep up with the pace of the professor's lectures, you need to do more than just study the textbook, but also prepare a lot outside of class.

In addition, according to the course arrangement, the professor will also require students to complete several student papers during the teaching period, and the score of the paper will directly affect the overall evaluation of the course.

Therefore, after the actual start of the course, in addition to the textbooks, Link also needs to study a lot of books related to the course according to the requirements of the professor, which usually takes up a lot of extracurricular time.

Fortunately, Link's current intelligence of 15.7 points has greatly improved his learning efficiency, coupled with his physical fitness that is far beyond ordinary people, and the time he needs to rest is also short, so that Link can complete such a compact course schedule.

Peggy's learning efficiency is much higher than Link's, and there is no need for arrangements like Link's need to do martial arts training and gun practice on weekends, so the time even seems to be abundant.

Caltech students, in addition to classes, spend most of their time in the library and study room, including Link's roommate Lang.

Of course, Link still knows how to combine work and rest, and plans to have half a day of relaxation time on both weekends and evenings, and this Friday afternoon, Link met an acquaintance in class.

This afternoon's class was a big class, and the format of this large class of dozens or hundreds of people and most of the small classes with only a dozen people were completely different.

One of the most important points is that the professors who take the big classes are equipped with a special teaching assistant.

Teaching assistants here are not full-time faculty members, but are held by senior students, which is a work-study position and a characteristic of American universities.

As a private research university, Cal Poly professors are experts in their fields, teaching is only part of their job, and more importantly, they are doing their own research.

Teaching alone can't teach the Nobel Prize, the Pulz Prize, or the Turing Award!

Moreover, as an internationally renowned professor, he can also teach undergraduate students in person, which is already worthy of the salary offered by the school, and the school cannot ask them for more.

Therefore, teaching assistants are needed to help them complete trivial tasks outside of teaching.

Teaching assistants have a lot of chores, but the main responsibility of teaching assistants is to correct the class papers assigned by professors.

The acquaintance Link met in this big class was Sophia, the assistant teacher of this course, and when Link and Peggy walked into the classroom together, Sophia was on the podium, preparing for the professor who had not yet arrived.

Seeing Sophia's situation, Link guessed that she was mostly working as an assistant coach, and Sophia noticed Link.

Finding out that the other party was a teaching assistant, Link was also in a good mood, after all, the teaching assistant held the right to evaluate the students' usual grades in schoolwork, and after a brief eye contact, Link confirmed that she had a good impression of herself.

Seeing that class was about to start, the two of them didn't speak, and Link and Peggy sat down in the first row.

When the time came, I saw a professor dressed in professional attire walking in in a hurry, and after standing on the podium, he did not greet each other, and directly began to lecture.

The professor's schedule is very tight, the class is stepping on the point, the class is the first to leave, and the preparation before class and the finishing work after class are handed over to the teaching assistant, which is also the standard practice of the professor of the big class.
