The general class of questions that some algorithm can answer in polynomial time is "P" or "class P". For some questions, there is no known way to find an answer quickly, but if provided with an answer, it can be verified quickly. The class of questions where an answer can be verified in polynomial time is "NP", standing for "nondeterministic ...
This article is a list of notable unsolved problems in computer science. A problem in computer science is considered unsolved when no solution is known or when experts in the field disagree about proposed solutions.
The results of the examinations are usually declared in the first week of May to Mid-June. In general, about 80% of candidates receive a passing score. [8] The Delhi High Court has directed the Central Board of Secondary Education and Delhi University to discuss the ways by which the results of the main exam, revaluation, and compartment exam can be declared earlier than usual so that ...

[40] Consequently, the Central Board of Secondary Education has put in place a system of "encrypted" question papers, which are supposed to be printed by the schools half an hour before the exam starts.
John Hopcroft brought everyone at the conference to a consensus that the question of whether NP-complete problems are solvable in polynomial time should be put off to be solved at some later date, since nobody had any formal proofs for their claims one way or the other. [citation needed] This is known as "the question of whether P=NP".
There are many streams students can choose for their 11 and 12 grades, including pre-medical, pre-engineering, humanities (or social sciences), computer science and commerce. Each stream consists of three electives and as well as three compulsory subjects of English, Urdu, Islamiyat (grade 11 only) and Pakistan Studies (grade 12 only).
It is intimately tied to many aspects of computer science: type systems for programming languages, the theory of transition systems, models of programming languages and the theory of programming language semantics. [6] Logic programming is a programming, database and knowledge representation paradigm that is based on formal logic. A logic ...
