A growing number of college students are applying to take entry tests for medical and dental (牙科的) schools among increasing graduate unemployment in Korea.

“I’ve decided to apply for the test to enter a medical college to become a doctor, changing from my original plan to prepare for a lawyer qualification exam in order to get a more stable job in the future,” said a 24-year-old college graduate, Lee, who majored in business administration during his undergraduate schooling.

The new medical and dental school system is getting popularity, attracting an increasing number of students every year since its appearance in 2004, as it is open to all college graduates regardless of their previous majors.

The Education Development introduced the new medical and dental education system, in which college students with bachelor’s degrees are allowed to study medicine or dentistry by taking the Medical Education Test (MET) and Dental Education Test (DET).

Ten medical schools and six dental colleges that have used the new system have received 4,377 applications (申请) for the entrance exams.

Applicants are getting younger compared with those in their 20s representing 76.9 percent of the total. The tests might be easier for students with biology and chemistry majors, but graduates from other majors are also applying for the tests.

Under the existing medical and dental education system, students should take a two-year premedical course followed by a four-year medical course.

Students graduating under the new medical or dental education system are given master’s degrees, while those graduates who studied under the previous system have bachelor’s degrees.

小题1:Why do more and more Korean students apply for medical schools?

C.Because medicine is easier to learn than other subjects.
