Every school year at Mount Carmel is divided into three trimesters. Each one lasts around twelve weeks. Each one ends with finals. Each one affects GPA. 

Yet students should not treat them equally.

Motivation shifts throughout the year. Weather changes, academic expectations increase, and adjust. What appears balanced on paper is anything but in reality. One MC student compares the school year to a story.

“The first one is the exposition of the story,” says sophomore James Weber. “The second one is the climax, and then the third one is like, ’Yay, it’s over!’”

The first trimester carries the most long-term importance, and students who underestimate it often spend the rest of the year trying to recover.

Freshmen experience the transition into high school immediately. The workload increases, pacing changes, and their responsibilities grow, and this might be the first time they are on trimesters. Freshman Jack Reilly finds that adjustment to be critical. 

“The first one is definitely the most important freshman year because that’s when you’re getting used to schoolwork in high school,” he says.

That early adjustment shapes confidence. Students who start strong often maintain momentum. Students who start poorly do not just “bounce back” but instead spend months trying to repair the damage. Algebra and Statistics teacher Mrs. Jennifer Smola reinforces this idea from a teacher’s perspective.

“[The first trimester] Kinda sets the tone for yourself,” she says. This is especially true in foundational subjects like math. A weak start makes everything else harder. She also makes the long-term impact clear when discussing GPA. 

“It’s really hard to bring up your GPA when you start with a crappy GPA freshman year,” says Mrs. Smola. Because GPA is cumulative, early grades follow students longer than they expect. 

“The first trimester is like your baseline,” says junior Jeremy Ingram. “It puts you in a trajectory for all four years.” Once the direction is set, changing it requires significant effort.

“In retrospect, [Freshman] will not realize how important the first trimester is for really setting the tone for the four years here,” says senior RJ Risos. 

Students may not feel the pressure immediately, but later they understand how much that beginning mattered.

If the first trimester sets direction, the second trimester exposes who can actually sustain it. By this point, teachers expect consistency. There is less adjustment and more performance, and the pace increases. 

“I’m no longer giving you leeway,” says Mrs. Smola. “It goes a lot faster.”

Faster pacing means less room for mistakes. Students must adapt quickly or fall behind. At the same time, winter affects energy and focus.

“People are scientifically not as active during the winter months,” says Risos. “They feel less energized.”

Lower energy during more demanding weeks creates a mismatch between effort required and motivation available. The second trimester is also interrupted by Christmas break. 

“It’s almost like I look at the second trimester as two mini trimesters,” says Mrs. Smola.

Instead of building continuous momentum, students experience disruption. Returning from break requires relearning before progressing. 

“It’s hard to remember all the information that you learned prior to Christmas break,” says Risos. 

On top of that, juniors and seniors prepare for AP exams and the SAT during this trimester, which Risos says can be a stressful time.

Some argue that the second trimester is easier because of Thanksgiving and Christmas breaks, as it provides time to relax and reset. However, rest does not automatically restore discipline. Long breaks often interrupt routines and increase procrastination. Instead of maintaining focus, students must rebuild it. When harder content is packed into shorter, uninterrupted weeks, pressure increases rather than decreases. 

Because it requires students to stay consistent during the least motivating time of the year, the second trimester subtly becomes the breaking point for many students. The breaks might be nice in the moment, but they can also make the second trimester more difficult instead of easier.

By the third trimester, the atmosphere changes. The weather improves. Major school events approach. Graduation is near for seniors. Students stop looking at how much farther they have to go and start looking at how much closer they are to graduation.

“Third trimester goes by the fastest because of the Walkathon,” says Weber reffering to the biggest student fundraiser of the year. Shortened weeks and school-wide events make time feel compressed. 

“100% there’s no debate,” says junior Nolan Esquivel. “Third trimester is the most enjoyable.”  

Enjoyment does not necessarily mean easier academics. It means the emotional pressure changes.

“They have given up pretty much,” says Mrs. Smola, referring to seniors after college acceptances arrive and nearing graduation.

Motivation shifts from long-term competition to simply finishing strong.

“If you’re at an A, you don’t have the looming threat of final exams,” says Risos, talking about some senior and AP classes.

The third trimester does not remove responsibility, but it just makes students think it has. Students can see the finish line, and the visibility makes everything feel lighter.

The three-trimester system divides the school year evenly, but they shape students differently. The first determines direction. The second tests resilience. The third changes perspective as the year comes to a close. The structure of the calendar may remain balanced, but the experience is not. 

Students who understand that rhythm can control their year instead of being controlled by it.
