Q. What are the 4 years of college called in the USA?

The four years of college in the United States are usually called undergraduate school. A typical educational journey is divided into four stages, each termed a "year," though the length of time varies somewhat depending on the institution. 

The first year of college is generally called the freshman year. The first round is full of the thrill of novelty and feeling one's way as students move from their comfortable high schools into a more unfamiliar landscape for higher education. 

Freshmen take preliminary courses, Browse through different academic fields, and orient themselves to the lively campus life.

The second year is often referred to as the sophomore year. Moving along the second year is often called a sophomore. At this stage, students are supposed to have developed clearer ideas about their interests.

In their sophomore year, students dig deeper into the specialization of their chosen major. They hone in on skills and deepen coursework. This is an important year to lay the academic foundations and prepare for more advanced challenges in the future.

The third year is called the junior year. At this time, students usually have clearer ideas about their academic or career goals. While junior year features more specialized coursework within a given major, internships and opportunities for experiential learning abound. 

In many cases, students begin thinking seriously about plans after graduation: whether to join the workforce or continue studying and pursue advanced degrees.

The fourth and final year is, therefore, termed the senior year. Seniors usually take advanced coursework and do capstone projects or comprehensive examinations that sum up their undergraduate studies. 

As students prepare to set off for another adventure next year, this is a time of reflection--thinking back on what they have accomplished over the last four years and preparing themselves with knowledge and skills.
