Prepare for engineering by building strong mathematics and science foundations, trying engineering design through practical projects, and checking the admission and placement rules for the universities you may apply to. Algebra, geometry, Algebra II and pre-calculus are useful foundations; calculus is valuable when available, but it is not a universal requirement for becoming an engineer.
Which math classes should you take?
Prioritize understanding the material in a steady sequence rather than racing through courses. Oregon State recommends algebra, geometry, Algebra II and pre-calculus, followed by calculus if it is available. It says calculus can help with preparation but is not necessary to become an engineer; mastery of the fundamentals matters. Princeton similarly advises broad mathematics study, including strong algebra II and pre-calculus, while encouraging students to take calculus when feasible.

Course names and expectations depend on your school system and the university. If your school does not offer an advanced course, ask a counselor about the strongest sequence available, approved dual-enrollment options or other local enrichment. Before relying on a course for admission, placement or credit, confirm how each target institution treats it.
What science should you study?
Physics is useful preparation, and chemistry is important for many engineering programs. Biology may also be part of a school’s recommended science sequence. The balance is not universal: universities publish their own expectations.
For example, Cornell Engineering specifies calculus, physics and chemistry among its applicant expectations, while the University of Texas at Arlington describes preparation that includes four years of science covering biology, chemistry and physics, plus an elective. These are institution-specific examples, not a shared rule for all engineering applicants.
How can you explore engineering before college?
Choose activities that let you investigate how things work and solve a defined problem. Oregon State suggests career and technical education courses such as manufacturing, electronics, robotics, engineering technology and computer-aided design. Depending on what is available locally, students might also try robotics, maker, coding, SkillsUSA or drone clubs.

Make a small design project
A project does not need expensive equipment. Start with a question or problem, identify constraints such as materials, time or size, sketch more than one possible solution, then make a simple prototype. Observe what happens, revise the design and explain what changed and why.

Random freezes, missing sound and display glitches usually trace back to one bad driver. Find and replace yours safely.Free scan · under a minuteThis approach reflects the National Academies’ description of engineering design as iterative, open to multiple solutions and a way to connect mathematics, science and technology with modeling and analysis. The goal is not just to build an object once; it is to learn from testing and improve a solution.
Learn what engineers do
Engineering includes different disciplines and kinds of work. Research programs and related occupations, and talk with engineers, engineering students or university advisers when possible. UC Merced’s advising guidance also highlights writing, engineering mathematics, study and time-management habits, and asking people in the field questions. These conversations can help you test your interests before choosing a major.

Do not treat one university’s admission guidance as the standard everywhere. Requirements and recommendations differ, and the cited university examples are from the United States; their course labels may not map directly to other national systems.
- Make a shortlist. Identify programs you might realistically apply to, including the country and engineering discipline where relevant.
- Read each program’s current guidance. Separate admission prerequisites from recommendations, placement expectations and advice about preparation.
- Check course and credit policies. Ask whether advanced, dual-enrollment or equivalent courses count for admission, placement or transferable credit.
- Ask when information is unclear. Contact the institution’s admissions or engineering advising office, and ask your school counselor how local course options compare.
The difference between advice and a requirement matters. Cornell’s specific expectations, Oregon State’s view that high-school calculus is not necessary to become an engineer, and Princeton’s guidance to pursue as much math as feasible while maintaining foundations address different institutional contexts. Verify the current rules for every program you are considering rather than assuming one applies to all.
