In 2015, content changes in the exam were instituted to make it entirely discipline-specific, with a plan of weaving general engineering subject matter (e.g. math and science fundamentals) throughout the exam.[2] Less of the "full breadth" of most traditional engineering undergraduate curricula will be captured with this approach - such as the broad math and science foundation spanning chemistry, physics, mechanics (i.e. statics and dynamics), materials science, computer science, electronics/circuits, engineering design, and the standard range of engineering mathematics (i.e. calculus, differential equations, statistics). A concern was that, while most undergraduate engineering students are in fact exposed to most of these subjects, they may not necessarily take courses in specialized topics such as thermodynamics and fluid mechanics.
