Is a grade d in mathematics a pass?

It's a failing grade, so yeah, it's bad. Most employers want to see a pass in GCSE mathematics, the same for most universities. My advice is to hire a tutor (not necessarily a professional, just anyone good at math who has done A-level mathematics; I taught like that for a while) and take it again. Alternatively, you could look into online tutoring services such as Spires, which offer experienced Spires online maths tutors. This grade correlates with a high D grade in the current GCSE system.

The passing grades range from A+ to D*. P is a passing grade, but it does not affect the student's academic score. Students can only receive an “I” grade if they have a passing average on coursework that has been completed and have well-defined parameters for completing course requirements that could result in a score better than the default grade. This score expresses the student's inability to demonstrate sufficient use of knowledge or application of Mathematics to achieve any of the grading scores below.

For a grade of C or better to replace a failing grade in cumulative G calculations, we imagine that this score would require students to demonstrate the use of higher-level content in questions where students must indicate the relevant mathematics and use the content correctly to solve complex problems. In addition, for the first 28 credits enrolled students attempt, a failing grade in a non-corrective or undeveloped 100-level course will be converted to an NC score. As of September 1, 1990, pursuant to the resolution passed by the Board of Directors of the City University of New York, an undergraduate student who obtains an academic or administrative failure score calculated on the cumulative average of grade points may retake the course and, if he or she approves course completion with a grade of C or better, that the failing grade is no longer computed in G. This resolution applies to grades of C or better received for courses that were retaken in the fall semester of 1990 and, subsequently, replace the index value of grades failures obtained in courses taken in autumn 1984 and beyond.

As indicated in the following table, each grade has a numerical value, which is used to calculate the grade point average (GPA).
