Lower Division Recommendations for Aspiring Software Engineers

The following recommendations are tailored for students targeting big tech and aiming for a specialization in computing, with a focus on software engineering:

Objectives

Be prepared for recruiting Sophomore year fall.
Be prepared for internship Sophomore year summer.
Knockout lower division courses in the least stressful manner.

Advised Courses

The following courses are advised for students to take in their lower division years:

Life Sciences 7A or 15* or Physiological Science 3--Just know if you take 7A get ready to meet all the premeds!
Mathematics 31A & 31B or Mathematics 3A & 3B & 3C--So this one is a little tricky. I personally took LS30A, 30B, and Stats 10 (you can petition stats 10 to count) but sometimes I regretted this decision. It is by far the easiest way to accomplish this requirement but 31A and 31B are requirements for linear algebra (33A) which is basis of Machine Learning. If you want to keep your options open, I would recommend 31A & 31B. If you don't gaf I would do the LS series.
Philosophy 7 or 8 or 9 or 23 or 31--
Physics 1A or 5A or 10* or 11* or Chemistry 14A or 17* or 20A or Linguistics 1 or 20*--It doesn't really matter, but if you want to go deeper into LLM stuff, I would go down the linguistics path.
Program in Computing 10ADO NOT TAKE PIC 10A, take CS31The PIC series at UCLA is an abomination. It theoretically is teaching you the same stuff as the CS series except its disjointed, varies by professor, and not nearly as good of a curriculum as the CS series.
Two courses from: Program in Computing 10B or 10C or 15 or 16A or 16B or 20A or 30 or 40A or Psychology 20A or 20B or 30 or Statistics 20 or 21Do not take anything in this list; CS31/32 will count for PIC10A-BI know you might be inclined to take something like Python or idk MatLab but if you go down that route you shoot yourself in the foot for all of the important CS upper divs that you will need to take. C++ might seem like a drag but once you learn a typed language it is so much easier to pick up untyped languages.
Psychology 10--AP Psych counts.
Psychology 85--Take this whenever the professor is good. I had Kelman and his class format was weird as hell, the material itself was very interesting though.
Psychology 100A**--Take as early as possible. Professor does not matter this class is chill af.
Psychology 100B**--Take as early as possible. Enrollment is annoying as hell!!

Recommended Course Schedule

A sample schedule incorporating these recommendations looks like this:

Y1 Fall: LS7A, Math 31A, Psych 10
Y1 Winter: CS 31, Math 31B, Ling 1, GE
Y1 Spring: CS32, Philos 7, Psych 85
Y2 Fall: Psych 100A, Psych 85, CS 35L, GE
Y2 Winter: Psych 100B, CS33, Math 61
Y2 Spring: CS 180, GE, Psych 120A

This schedule allows students to meet objectives and frontload upper division preparation. The most important courses by far are CS32 and CS35L for recruiting and internships respectively. You will also get a head start on your upper division classes. Be prepared for recruiting Sophomore year fall (CS32) Be prepared for internship Sophomore year summer (CS32/CS35L/CS33) Knockout lower division courses in the least stressful manner

To prepare for the upper division classes, I recommend supplementing your learning with the following:

CS 33 (Computer Architecture)
CS 35L (Software Construction)
Math 61 (Discrete Math)
CS 180 (Algorithms & Complexity)

Upper Division Classes

Now these are more your choice and really just depend on what is offered in each quarter. I'll put together a list of CS classes that you 100% should take and that's all that is really necessary. For everything else, just follow the guidelines and take interesting/smaller classes.

CS 111 (Operating Systems)
CS 131 (Programming Languages)
CS 180 (Algorithms and Complexity)
CS 118 (Networking) or CS 143 (Databases)

Graduate Studies: M.S. and Ph.D. Programs

UCLA offers both Master of Science (M.S.) and Doctor of Philosophy (Ph.D.) programs in Computer Science, each with its own set of requirements and specializations.

Master of Science (M.S.) Program

M.S. students are not required to select a major field. A total of 9 courses are required to fulfill the requirement towards the M.S. degree under Plan I: 7 must be formal courses (taken for letter grades), and at least 4 of the 7 must be 200-level courses in Computer Science. 2 courses (or 8 units) must be CS 598, which involves work on the thesis. The remaining 3 courses are elective courses, which may be 100- or 200-level courses in Computer Science or 200-level courses in a closely related discipline, e.g. Electrical and Computer Engineering, Statistics, Mathematics, etc.

A total of 9 courses are required to fulfill the requirement towards the M.S. degree under Plan II: At least 5 courses must be 200-level courses in Computer Science (taken for letter grades). 500-level courses cannot be applied. The remaining 4 courses are elective courses, which may be 100- or 200-level courses in Computer Science or 200-level courses in a closely related discipline, e.g. Electrical and Computer Engineering, Statistics, Mathematics, etc.

Master’s degree students must satisfy the computer science breadth requirement by the end of the fourth quarter in graduate residence at UCLA. In addition, for the M.S. The master’s Capstone Project requirement is satisfied through satisfactory completion of an individual project under the direction of the student’s faculty adviser.

The average (normative) length of time for students in the M.S. program is six quarters. The maximum time allowed for completing the M.S. degree is seven quarters from the time of admission to the M.S.

Doctor of Philosophy (Ph.D.) Program

Normally, the student takes courses to acquire the knowledge needed to prepare for the written and oral preliminary examinations, and for conducting Ph.D. research. The basic program of study for the Ph.D.

To satisfy the major field requirement, the student is expected to attain a body of knowledge contained in five courses, at least four of which must be graduate courses in the major field of Ph.D. research. Each minor field normally embraces a body of knowledge equivalent to two courses, at least one of which must be a graduate course. Major and minor field courses are selected in accordance with the guidelines specific to each field. These guidelines for course selection are available from the department’s Graduate Student Affairs Office.

Doctoral degree students must satisfy the computer science breadth requirement by the end of the 9th quarter of study and before taking the Oral Qualifying Examination. For the Ph.D. degree, the student must complete at least three quarters of Computer Science 201 with grades of Satisfactory (in addition to the three quarters of CS 201 that may have been completed for the M.S.

The written qualifying examination consists of a high-quality paper, solely authored by the student. This paper can be a research paper containing an original contribution, or a focused critical survey paper. The paper should demonstrate that the student understands and can integrate and communicate ideas clearly and concisely. The paper should be approximately 10 pages, single-spaced, and the style should be suitable for submission to a first-rate technical conference or journal. The paper must represent work that the student did as a UCLA graduate student. After submission the paper must be reviewed and approved by at least two other members of the faculty.

After passing the preliminary examination, the breadth requirements, and course work for the major and minor fields, the student should form a doctoral committee and prepare to take the University Oral Qualifying Examination. A doctoral committee consists of a minimum of four members. Three members, including the chair, are inside members and must hold appointments in the student’s major department in the School. The outside member is normally a UCLA faculty member outside the student’s major department. The nature and content of the University Oral Qualifying Examination are at the discretion of the doctoral committee, but ordinarily include a broad inquiry into the student’s preparation for research.

The student is expected to pass the Written Qualifying Exam within the first six quarters (two years), complete the breadth requirements and major and minor field courses within the first nine quarters (three years), pass the Oral Qualifying Exam within nine quarters ( three years), and complete the Ph.D.

Data Science and Computer Science: A Comparative Overview

Data science and computer science have become two of today’s fastest-growing career paths, driven by rapid advances in technology and expanding industry demand. For aspiring technology and engineering leaders, choosing between the two fields can be challenging. While data science and computer science both emphasize technical skills, they focus on different aspects of technology and problem-solving.

The work of data scientists revolves around developing the algorithms and models that enable data analysts to extract knowledge from structured and unstructured data. Data science is a highly interdisciplinary field, requiring skills from a variety of technical disciplines. Students pursuing a data science engineering degree gain technical knowledge from a variety of areas like computer science, mathematics, business, information technology, ethics, graphic design, communication and more.

Computer science (CS) can seem somewhat self-explanatory: the study of computer hardware, software and the systems related to them. However, this field is very large and offers a variety of specialization areas. Some computer science professionals focus on the theoretical aspects of the field, researching how computational systems may be able to solve problems in the real world.

Overlapping Skills and Knowledge

Data science and computer science are closely related, as data scientists leverage some of the same skills and knowledge areas as computer scientists. While the two fields share technical foundations, the way they apply that knowledge differs significantly. Data science emphasizes the creation of models that enable analysis and interpretation of data. It tends to guide the decision-making process in organizations across a variety of industries, especially in business operations, health-care analysis and finance. Data science professionals may find careers developing predictive analytics models, gathering business intelligence, engineering machine learning solutions and aggregating research insights. Many data science professionals also use large language models, such as ChatGPT, as a model for various machine learning projects.

Computer science uses development frameworks and simulation tools for system testing and other applications. The curriculum of a data science program will offer foundational courses that reflect the field’s focus, required skills and common tools: statistics, predictive modeling, machine learning, data visualization and ethics. Courses in data visualization, AI ethics, or natural language processing can fine tune a data science program even further. Computer science programs run the gamut in terms of coursework, and courses may cover algorithms, data structures, operating systems, software engineering, databases and networking.

Data science and computer science can be highly interrelated - data science is often considered to be a subfield of computer science, especially in an academic setting. Data scientists leverage computer science knowledge every day when they write code, build machine learning modules and deploy programming-based solutions. And computer scientists need to at least understand data science to build systems that enable organizations to analyze data efficiently. They also share many practical similarities and have overlapping skill sets. Both fields require programming skills, knowledge of algorithms and problem-solving abilities. Data structures, databases and software tools are used in each field. These similarities in foundational skills enable technology professionals to pivot from one field to another, provided that they gain the additional specialized knowledge needed for each field.

Career Paths

Potential Careers in Data Science vs. Data science includes more than data analysis, and computer science can offer more than software development roles. Computer Scientist vs. Data scientists create algorithms that enable analysts to gather insights from datasets, often in business analytics, health care, finance or tech.

Choosing the Right Path

Choosing which field is right for you can depend on a variety of factors. It is important to remember that a career in either area is not guaranteed, but advanced study can provide aspiring professionals with crucial skills to potentially improve their chances. Generally, a career in data science suits those who like analyzing information, spotting trends and using data to support better decision-making. Computer science is a good fit for those who enjoy programming, developing algorithms and designing software systems.

Choose data science if you want to build algorithms, analyze data, make predictions through machine learning and meaningfully contribute to big-picture business objectives. Computer science is a better fit if you enjoy designing systems, building software and creating or improving computer technologies. Or, you can potentially combine both areas. Additional considerations to keep in mind include preferred industries, work environments and long-term career goals.
