Are there any university accepting students for computer based programs but without maths?

Many universities do not require math, and many will not even require computer science at the A level because most degrees are taught from the ground up (unless they state otherwise). The UCAS points are the most important. My advice is to look around, attend open days, and speak with various universities to see what they require. Keep in mind that every university is unique. Finally, you could mention your CS material in your personal statement, application, and interviews to make yourself appear more impressive, but don't worry because you'll do fine. The following are the requirements for pursuing an MS in computer science in the United States:

Candidates should have a bachelor's degree in computer science or a related field. On a four-point scale, aggregate GPAs should be 3 or higher.
The equivalent mark is usually 83-86%, with a B being the equivalent grade.
You should submit your GRE scores, with an average score of 292-328.
You should also submit your results from English languages proficiency exams such as IELTS or TOEFL.
