Hello,
Whether the question paper of the 2023 district-level B.Sc. Mathematics exam has or hasn't been issued depends upon the university you're referring to, or the college, or the education board. If so, then universities and colleges quite often post past question papers for students to prepare and get ready for any exams. Such pieces of paper can usually be found on the official website of that institution, department, or even through some student forums.
If it is a state or district level B. Sc. Mathematics examination then contact the exam cell or concerned academic department of the relevant university. They will also be able to provide sample question papers from previous years for practice. In addition to these there are websites providing study material, which offer sample question papers or previous year papers for practice. Such papers guide a student through the kind of pattern of the examinations, the type of questions that may be asked, and the important topics.
You can also get the study material from fellow classmates or lecturers if the question papers are not readily available.
