URIECA FAQ

We've included some frequently asked questions about URIECA. Please click on a question to display the answer. If you have additional questions not covered here please email Jennifer Weisman (jweisman@mit.edu).

What do I do if I have completed one or two of the modules in 5.35, 5.36, or 5.37 as a chemistry major but then decide to change majors?

Please send an email to Jennifer Weisman (jweisman@mit.edu) and Mariusz Twardowski (mariusz@mit.edu) requesting that the subject number be changed to the “U" equivalent and that a letter grade be assigned for the completed work (either for 4 units or 8 units depending on the number of modules completed). 

What do I do if I have completed one or two of the modules as a non-chemistry major and then decide to become a chemistry major?

Complete the subject with the “U” designation.  You will receive credit for completing the entire subject when you complete the final module.

I am a non-chemistry major upperclassman and have already taken 5.310. What should I register for if I want to take more laboratory classes?

The first subject for upperclassmen non-chemistry majors is 5.310 Laboratory Chemistry. Students who desire to take more laboratory chemistry modules in the URIECA curriculum but who do not want to complete all modules in a given subject should register for the “U” equivalent of the subject (5.36U, 5.37U).

Note: For a complete description of chemistry modules, please see the Module Descriptions page.

What URIECA laboratory classes do I need to take if I'm pursuing a chemistry minor?

The required laboratory subject for minors in chemistry is 5.310. Taking 5.36, 5.37, or a total of 12 units of credit from the modules in 5.36U or 5.37U satisfies one elective subject of a chemistry minor. For more information about pursuing a chemisty minor, please click here.

How do I register for individual modules?

Each module of a URIECA subject is worth 4 units of credit, and students preregister for URIECA modules in a two-step process. In addition to the usual preregistration process through WebSIS, students must also sign up for specific modules through the Course 5 website. Failure to sign up for the modules could result in being denied access to them.

To sign up for specific modules, students may access the appropriate online form through either the online subject listing for each class or by following the appropriate link(s) below:


Important note regarding Registration Day: Because these courses are set up as variable-unit subjects, students must verify the number of units that they are taking for each URIECA subject on their Registration Forms. Students registering for any non-U subject (5.35., 5.36, 5.37, 5.38) may register for 4, 8, or 12 units of credit per term, up to a maximum of 12 units per subject. Students registering for any U subject (5.35U, 5.36U, 5.37U) may register for 4 or 8 units of credit per term, up to a maximum of 12 units per subject.

How are grades assigned for 5.35, 5.36, 5.37, and 5.38?

The URIECA subjects are J-graded.  A J-graded subject is one where the final subject grade is not recorded until 12 units, or three modules, are completed. Students will receive a grade of J in each semester that they complete less than three modules in the subject.  Once three modules are complete, each J grade on the transcript will appear as J-X, where X is the grade for the subject. 

Note that although 5.36 and 5.37 each carry three modules totaling 12 units, the modules are not offered in the same semester. Students will not be able to register for 12 units of these subjects in any one semester.

How are grades assigned for 5.35U, 5.36U, and 5.37U?

Students are assigned a grade at the end of each semester for 4 or 8 units depending on the number of modules registered for and completed. Subjects with “U” designation may be repeated for up to 12 units.

Can I register for URIECA modules as a first-year student?

Yes. First-year students, with 5.111, 5.112, or 3.091 as a prerequisite, may register for some of the 5.35U modules allowing them to explore the chemistry curriculum and to acquire hands-on laboratory experience. First-year students, with 5.111, 5.112, or 3.091 as a prerequisite and 5.12 as a corequisite may register for 12 units of 5.35.

I am a non-major and need to take Chemistry CI-M classes. What class should I register for?


Chemical Engineering (Course 10)

  • For a Course 10 or 10-C degree, students interested in taking a Chemistry CI-M subject should take 5.36
  • Students who don't want CI-M credit but wish to take a subset of 5.36 modules should register for 5.36U


Biology (Course 7)

  • For a Course 7-A degree, students interested in taking two Chemistry CI-M subjects should take 5.36 and 5.38
  • Students who don't want CI-M credit but wish to take a subset of 5.36 modules should register for 5.36U


Materials Science and Engineering (Course 3)

  • For a Course 3-A degree, students interested in taking two Chemistry CI-M subjects should take 5.36 and 5.38
  • Students who don't want CI-M credit but wish to take a subset of 5.36 modules should register for 5.36U
