Computer Sciences MCQs

Computer Science MCQs related to the Computer Science Course, Degree, Subjects, and Syllabus are given to pass the initial academic tests of Technical Cadet Course (TCC) and Lady Cadet Course (LCC).

Girls who have their degrees in computer science engineering or simple in computer science at master / BS level can apply in Pak Army Lady Cadet Course to become a lady officer.

If you are worried about multiple choice questions of computer science then see the questions given below which are past papers mcqs taken from the previous candidates.

In academic tests of Lady Cadet Course (LCC), girls have to clear intelligence tests which contains verbal and non verbal mcqs of 100 question or sometimes 75 questions in total.
