Indiana University

 

Indiana University is located in the state of Indiana. The state is called the Crossroads of America because it is centrally located in the midwestern region of the United States, and a great deal of the country’s commercial activity passes through Indiana.

 

Indiana University is composed of eight campuses, with the original and largest campus located in Bloomington, Indiana. IU Bloomington also has the most international students—more than 4,000 students from more than 125 countries study on the Bloomington campus.

About Indiana University

Indiana University encourages your interest in studying in the United States. We are a diverse university with international students from more than 130 countries. Here are some details about the U.S. academic system.

Grades

Professors give letter grades to show the quality of a student’s work. The grade tells how well the student is performing on tests, research papers, and class participation. Most colleges or universities require that students maintain a minimum grade point average to continue their studies. Here are the grades and the grade point averages:

A+ (4.0)

A (4.0)

A– (3.7) (excellent)

C+ (2.3)

C (2.0)

C– (1.7) (average)

F (0) (failure)
B+ (3.3)

B (3.0)

B– (2.7) (above average)

D+ (1.3)

D (1.0)

D– (0.7) (poor)

 

Academic Year

The university academic year at IU is made up of two semesters. The fall semester is from August to December. The spring semester is from January to May. It is a good idea for international students to enter U.S. universities in fall. Most new students enter at this time, so they can adjust together.

 

Classroom Learning

Some classes are large lectures with over 100 students. Others are smaller classes and "seminars" (discussion classes) with fewer students. Lecture courses are often split into smaller groups or "sections." The sections meet separately to discuss the class material.

Professors usually assign readings each week. They also require several written reports or "papers" each semester. You are expected to keep up with the readings so you can join in discussions and understand the lectures. Science students also must do laboratory work.

The Degrees You Can Earn

Bachelor's Degree

U.S. students can go on to college or university after finishing high school (12th grade). Therefore, you need to know which level of education in your country matches up with the 12th grade in the United States. The International Admissions Office can help you with this.

Upon entering a college or university, students work toward their bachelor’s degree during the first four years. Students in the first year are called "freshmen." They are "sophomores" in the second year. "Junior" and "senior" refer to the third and fourth years.

The U.S. undergraduate educational system is different from many other systems because students have more control over their courses. Also, students are not typically admitted directly into their "major" field of study. Instead, most undergraduates are in general studies programs until just before their junior year.

Students must take a certain number of courses in areas outside their major department or field in order to earn a bachelor’s degree in the United States. This is based on the philosophy that students at the undergraduate level get the best education by being exposed to several areas of study.

In some degree programs, students also choose a "minor" field that may or may not be closely related to their major. For example, a student could choose to major in marketing and minor in French. Students also choose some "elective" (extra) courses in other subjects.

 

Master’s Degree

A master’s degree follows the bachelor’s degree. It involves more study of a certain subject. This degree is required in some professions. The M.B.A., or Master of Business Administration, is a popular degree that usually takes two years. Some master’s programs take only one year.

Doctoral Degree (Ph.D.)

The doctoral degree is the highest degree you can earn in the United States. Examples include Ph.D. (Doctor of Philosophy), J.D. (Doctor of Law), M.D. (Doctor of Medicine), and D.D.S. (Doctor of Dental Surgery).

The Ph.D. requires course work, an examination, original research, and a dissertation. Most Ph.D. programs require at least three years of study after the master’s level. Most students take longer to finish this degree.

The first two years include classes and seminars. For another year or more, students will do research and write a thesis or dissertation. A dissertation is a written report of your original doctoral research. This paper must include views, designs, or research that has not been published before.

Students must pass a qualifying examination to get into the Ph.D. program. Later, they must pass an oral examination on the same topic as the dissertation.

International unit

In pharmacology, the International Unit is a unit of measurement for the amount of a substance, based on measured biological activity or effect. "International Unit" is abbreviated as IU, or as UI from the French unité internationale, or as UI from the Italian unità internazionali, or as IE from the German Internationale Einheit.

The unit is used for vitamins, hormones, some medications, vaccines, blood products, and similar biologically active substances. Despite its name, the IU is not part of the International System of Units used in physics and chemistry.

Variance

The precise definition of one IU differs from substance to substance and is established by international agreement for each substance. There is no equivalence among different substances; for instance, one IU of vitamin E does not contain the same number of milligrams as one IU of vitamin A.

Equality

To define an IU of a substance, the WHO Expert Committee on Biological Standardization provides a reference preparation of the substance, arbitrarily sets the number of IUs contained in that preparation, and specifies a biological procedure to compare other preparations of that substance to the reference preparation. The goal in setting the standard is that different preparations with the same biological effect will contain the same number of IUs.

 

Equivalency

For some substances, the equivalent mass of one IU is later established. If that happens, the former IU definition for that substance is officially abandoned, in favor of a newly established weight. However, the unit count often remains in use nevertheless, because it is convenient. For example, vitamin E exists in a number of different forms, all having different biological activities. Rather than specifying the precise type and mass of vitamin E in a preparation, for the purposes of pharmacology it is sufficient, simply, to specify the number of IUs of vitamin E.

Mass equivalents of 1 IU

  • Insulin: 1 IU is the biological equivalent of about 45.5 μg pure crystalline insulin (1/22 mg exactly).
    This corresponds to the old USP insulin unit, where one unit (U) of insulin is equal to the amount required to reduce the concentration of blood glucose in a fasting rabbit to 45 mg/dl (2.5 mmol/L).
  • Vitamin A: 1 IU is the biological equivalent of 0.3 μg retinol, or of 0.6 μg beta-carotene in the USA, and of 0.3 μg beta-carotene in Canada

 Difference from unit of enzyme activity

The IU should not be confused with the enzyme unit, also known as the International unit of enzyme activity and abbreviated as U. Forrás: en.wikipedia.org
