IMPORTANT NOTES – Preparation for the Major

Students must earn a grade of C- or better in each prep course and achieve an overall GPA of 2.0 in the prep for the major. Students receiving grades of below C- in two prep courses, either separate courses or repetitions of the same course, are subject to dismissal from the major.

• Students who complete CHEM 20A can move to the 14 series starting with 14B, or after taking 20A, 20B, students can take 14BL, 14C, 14CL*, 14D, or after taking 20A, 20B, 20L, may take 14C, 14CL*, 14D. Students who transfer chemistry credit from another school for 20A, 20L, can take 14B, 14C, 14CL*, 14D.
• The CHEM 14 series is unique to UCLA – there are no equivalents at other schools and must be taken in its entirety at UCLA.

*CHEM 14CL or CHEM 30BL is not required on the major, but most professional schools and possibly some graduate schools still require an organic chemistry lab.

IMPORTANT NOTES – Applying Independent Research towards MCDB Major Requirements

To enroll in MCDB 196A-B, 198A-D, or 199A-D, students must be conducting research in an MCDB-approved lab. The list of approved faculty research mentors is available on our website: https://www.mcdb.ucla.edu/undergraduate-research/ . A maximum of 12 units of MCDB research (MCDB 196A-B, MCDB 199A-C, MCDB 198A-C) may be applied towards major requirements.  Applying Independent Research towards the Lab Requirement MCDB 196A/B and MCDB 180A/B Students may apply for these courses during their third or fourth year. Application instructions can be found here: https://www.mcdb.ucla.edu/mcdb-196a-and-196b/.  MCDB 196B fulfills the Lab Requirement. MCDB 196A, 180A, and 180B (total 8 units) apply towards the 20 units of upper-division electives required for the major. MCDB 196B, 198B/C, or 199B/C and MCDB 145 MCDB 145 is only offered in Spring quarter. Students must apply for the course in Winter quarter.  MCDB 145 is taken concurrently with an MCDB upper-division research course. The research course fulfills the Lab Requirement. MCDB 145 (4 units) applies towards the 20 units of upper-division electives required for the major.  If you take MCDB 104AL, 187AL, or 150AL to fulfill the Lab Requirement, up to 12 units of MCDB research (MCDB 199A-C or MCDB 198A-C) apply towards the 20 units of upper-division electives required for the major.

Requirements for the B.S. degree established by the College of Letters & Science are listed in the UCLA General Catalog. A total of 180 quarter-units are required for the degree. 60 of the 180 units must be upper division (courses numbered 100-199). Please note that the MCDB major requirements satisfy 49 upper-division units.

SCHEDULING TIPS

• Not all electives are offered every year. Please consult the Schedule of Classes or the appropriate department.
• When planning your classes, please make sure you have accounted for all prerequisites for any upper-division class in which you plan to enroll. Courses may even have upper-division prerequisites.
• Some electives are restricted to the department’s own majors during first pass enrollment appointments. For example, you must wait until your second pass to enroll in MIMG 101, because it is restricted to MIMG majors during first pass.
