About this paper

CSC 303: University of Buea First Semester Examination 2025/2026, 30/01/2026, 2hrs, Amphi 750, Nyanga B. \& Mukete S.E., University of Buea, Faculty of Science, Dept of Computer Science: the stated instructions reference a 'Section C' that does not appear anywhere in the 3-page source, flagged rather than fabricated; a handwritten student attempt at Q3(a) and a handwritten addition to Q3(b)(iv) are both flagged and not used as source. Section A's Boolean-expression/function definitions, a De Morgan's-Theorem reduction of a 6-variable complemented expression (flagged two-vs-three-factor template mismatch against the question's own stated $(R+ST)(\bar U+V+W)$ form, resolved by working directly from the derived expression rather than forcing an artificial relabelling), and a modulo-16-counter/three-course exam-supervision word problem (truth-table-construction method, K-map/grouping analysis, logic gates, oscilloscope-waveform description, sequential-vs-combinational distinction, S-R flip-flop structure); Section B's 33-item MCQ block on assemblers, ISA/addressing modes, CISC/RISC, and memory-system theory, with the source's own '37-item' heading flagged as a count mismatch (only 33 items present in the available scan) and one item (full form of ISA) flagged for having no fully correct option among those printed.
