WGU course completion

D667 Precalculus, completed for you

At a glance

Last updated

D667 Precalculus (MATH 1040, 4 CUs in the September 2026 WGU catalog) is the precalculus gate of six WGU math and science education tables: term 3 of the B.S. Mathematics Education (Secondary) and its Educational Studies counterpart, and term 5 of the secondary chemistry and physics science education degrees and their Educational Studies counterparts. Functions, trigonometry, systems of equations, analytic geometry, and sequences and series, with a catalog-stated college algebra prerequisite. Coursework Ninja completes D667 done-for-you, fixed quote in writing first. From $99. Independent of WGU.

Next question: what does D889 Trigonometry, the term-4 course that follows D667 on the math education path, cover?

Per WGU's published description, D667 builds on previous math courses to deepen fundamental concepts and problem-solving skills in preparation for calculus and professional success: functions, trigonometry, systems of equations, analytic geometry, and sequences and series, taught through interactive learning experiences and real-world applications. The catalog states it plainly: successful completion of a college-level algebra course is a prerequisite. In the same six tables, that prerequisite is C278 College Algebra, scheduled exactly one term earlier.

Six catalog tables carry D667. The B.S. Mathematics Education (Secondary) and its Educational Studies counterpart place it in term 3, between the algebra gate and D889 Trigonometry. The four secondary science education tables place it in term 5, where chemistry and physics candidates meet functions and trigonometry between their biology and physics content rows. It is 4 CUs, it has a prerequisite behind it, and on the math education path it feeds directly into calculus: the course where a stall cascades. Message us the code and where you stand, and we quote a flat price in writing.

  • Fixed quote in writing before any work, singles from $99
  • 6 education tables: term 3 math education, term 5 chemistry and physics education
  • Catalog-stated college algebra prerequisite: C278 sits one term earlier in the same tables
  • Folds into the $3,000 bachelor's package with the 6-month guarantee

Every full package includes the written 6-month guarantee: we finish the remaining CUs under the agreed plan, or you do not pay. Packages: Bachelor's $3,000 · Master's $3,500 · both $5,500 · single assessments from $99.

What D667 completion covers

The D667 assessment

WGU does not publish assessment formats in the catalog. Student communities consistently report a proctored objective assessment (OA) for the precalculus course, consistent with how the education degree paths describe their quantitative gates. We confirm the current format for your catalog year at intake, and the fixed quote covers whichever assessment D667 carries.

Functions as the through-line

The description leads with functions, and the scored work agrees: families of functions, their graphs, transformations, and behavior. This is the vocabulary all of calculus is written in, so the assessment weights it heavily.

Trigonometry

The trigonometry row is the part career-switchers fear most: ratios, the unit circle, identities, and equations. On the math education path D889 Trigonometry goes deeper afterward; in D667 the trigonometry questions are applied and graph-heavy rather than proof-heavy.

Systems, analytic geometry, sequences and series

The description's other three pillars: systems of equations, analytic geometry, and sequences and series. These rows are mechanical and high-yield, the fastest points on the assessment for a prepared candidate and silent point-leaks for an unprepared one.

The prerequisite chain

The catalog states college algebra as the prerequisite, and C278 sits one term earlier in all six tables. On the math education path, D667 then feeds D889 Trigonometry in term 4 and D890 Calculus I in term 5. A stalled D667 does not stay a single-course problem, which is exactly when a fixed-quote completion keeps the ladder intact.

Full degree plan integration

D667 alone is a single from $99. On a remaining list in any of the six education tables it folds into the flat bachelor's package at $3,000, every remaining academic CU under the written 6-month finish guarantee.

Bottlenecks

Where D667 stalls future teachers

D667 stalls the same student in two different programs: the math education candidate who needs it as the calculus on-ramp, and the chemistry or physics education candidate who thought the math was behind them. These are the stalls we take over most often.

  • Math education candidates whose algebra credit transferred but whose trigonometry did not survive the transfer.
  • Science education candidates meeting functions and identities at term 5 with chemistry and physics exams competing for the same weekends.
  • Students who can work through trigonometry when it is in front of them and cannot produce it cold under exam conditions.
  • The cascade risk: on the math path, a slipped D667 pushes trigonometry and calculus, and the degree's back half slides a full term.
  • Working teachers studying piecemeal across a semester of grading periods and never reaching exam readiness in one stretch.

Questions, answered

Per the September 2026 WGU institutional catalog, Precalculus (MATH 1040, 4 CUs) builds on previous math courses for a deeper understanding of fundamental concepts and problem-solving in preparation for calculus: functions, trigonometry, systems of equations, analytic geometry, and sequences and series, through interactive learning experiences and real-world applications. The catalog states that successful completion of a college-level algebra course is a prerequisite.

Per the current catalog, 6 tables: term 3 of the B.S. Mathematics Education (Secondary) and the B.A. Educational Studies in Secondary Mathematics Education, and term 5 of the B.S. Science Education (Secondary Chemistry), the B.S. Science Education (Secondary Physics), and both Educational Studies counterparts.

WGU does not publish assessment formats in the catalog. Student communities consistently report a proctored objective assessment (OA) for the precalculus course, consistent with how the education degree paths describe their quantitative gates. We confirm the current format for your exact catalog year at intake, and the fixed quote covers whichever assessment the course carries.

Per the current catalog, the B.S. Mathematics Education (Secondary) runs D889 Trigonometry (MATH 2110) in term 4 and D890 Calculus I (MATH 2120) in term 5, directly behind D667 in term 3. On the science education paths D667 is followed by the physics and specialty science rows rather than more math. Wherever it sits, the code on your program plan is what we quote against.

Yes. The prerequisite is a catalog statement about the course's assumed starting point, not a condition on who can finish it with help. We complete the course as a single from $99 with the format confirmed for your catalog year, or inside the $3,000 bachelor's package if it sits on a longer remaining list.

One course starts at $99, with the exact figure fixed in writing once we know where you stand. If D667 is one row on a longer remaining bachelor's list, the bachelor's package is $3,000 flat with the written 6-month finish guarantee covering every academic course on the plan.

Yes. The licensed-teacher M.A. Mathematics Education tracks run this material as one course: C647 Trigonometry and Precalculus (MATH 6321, 2 CUs), term 1 of both the Middle Grades and Secondary tracks. Where the bachelor's path gives you two courses and two terms, D667 and D889, the graduate track compresses both into a single 2-CU course, and it has its own completion page under /courses.

No. We are an independent paid completion service, not affiliated with, endorsed by, or sponsored by Western Governors University. WGU provides its own instructors, mentors, and evaluators; Coursework Ninja is separate, for students who want this course finished on a fixed date.
