Tools you'll use
Exam pattern
Total 100 marks. Paper 1 (Theory) 70 marks, 3 hours: Part I (20 marks) compulsory short-answer questions covering the whole syllabus; Part II (50 marks) with Section A and Section B (10 marks each) and Section C (5 marks), candidates answering set numbers of questions. Paper 2 (Practical) 30 marks, 3 hours: candidates write a working Java program for one of three given problems, evaluated by a visiting examiner.
Practical / project
Paper 2 is a 3-hour, 30-mark practical conducted in BlueJ/JDK where students design, code and test a Java program for one of three problems (assessed on planning, coding, output and viva). Programs are documented in a practical file/lab record maintained through the year, reflecting algorithm design, data structures and OOP work.
Who it's for
ISC (CISCE) Class 12 students taking Computer Science (868) who want structured, syllabus-aligned coaching in Java programming, theory and the BlueJ practical exam.
What's included

Why study Computer Science (with Java)?
ISC Class 12 Computer Science (paper 868) is a 100-mark subject split into a 70-mark Java theory paper and a 30-mark BlueJ practical, which makes it a high-scoring board subject when programming and Boolean algebra are understood properly rather than crammed. The Java-based syllabus builds genuine object-oriented thinking, recursion and data-structure skills that directly feed into university computer science and engineering. Because much of the paper rewards correct logic and clean code, a student with strong fundamentals can convert this subject into one of their best ISC scores. Studying it live with structured notes, solved papers and consistent practice closes the gap between understanding a concept and writing it under exam conditions.
The course builds core object-oriented programming, recursion and data-structure foundations in Java that map directly onto B.Tech/BE Computer Science, BCA and B.Sc CS coursework. These same fundamentals (classes, inheritance, stacks, queues, linked lists, trees and Big O analysis) are the basis of software development, data structures and algorithms interviews used across the IT industry. It also gives an early, credible starting point for fields like software engineering, data and AI/ML, where strong programming logic is essential.
