Is this course right for a Kolkata student?
Most Kolkata schools follow the West Bengal Board (WBBSE/WBCHSE), with CBSE, ICSE/ISC and Cambridge schools alongside. We teach the CBSE, ICSE/ISC, Cambridge IGCSE, GSEB and NIOS computer subjects, not the WBBSE/WBCHSE computer paper itself, so this course suits a Kolkata student in one of those schools.
What Java covers
The course follows the full syllabus, 9 units.
- Object-Oriented Foundations
Object-oriented programming paradigm vs procedural; Principles of OOP: data abstraction, encapsulation, inheritance, polymorphism; Objects and classes; class as a composite/user-defined data type; Introduction to Java: applications vs applets, JVM, byte code, compilation process - Java Language Basics
Character set, tokens, identifiers, literals; Keywords, escape sequences, ASCII and Unicode; Primitive data types and variables; Type conversion: implicit (coercion) and explicit (casting) - Control Flow and Iteration
Conditional statements: if, if-else, nested if, switch-case; Iteration: while, do-while, for loops; Nested loops; Jump statements: break and continue - Classes, Objects and Methods
Defining classes, instance variables and methods; Constructors: default and parameterised; constructor overloading; Access specifiers and encapsulation (private data, public accessors); User-defined methods; pure and impure methods; method overloading - Arrays and Strings
Single and double dimensional arrays; Array traversal, searching (linear, binary) and sorting (selection, bubble); String class and common methods: length, charAt, substring, indexOf, concat, replace, compareTo, equals; StringBuffer basics; manipulating and comparing strings - Inheritance and Polymorphism
Base (super) and derived classes; extends keyword; Member access in derived classes; protected visibility; super keyword; redefinition and method overriding; Abstract classes and abstract methods; the Object class - Recursion
Concept of recursion and the call stack; Recursive methods: factorial, GCD, Fibonacci, power; Recursive binary search; Base case vs recursive case; number-base conversions - Data Structures and Collections
Stacks, queues and dequeues; implementation via classes; Defining data structures through interfaces with multiple implementations; Singly linked lists: algorithm and implementation; Binary trees and tree traversals (conceptual)

Students from around Kolkata
A student anywhere in Kolkata can take Java with us — Ballygunge, Bengal, Lake or Martiniere included — because the class is online and there is no centre to travel to. Kolkata sits in West Bengal, where the West Bengal Board (WBBSE/WBCHSE) runs alongside the national boards, so we are asked about both.
How Kolkata students attend
Every class is live at Indian Standard Time, in a small batch or one-to-one. Nothing is pre-recorded, so a student in Kolkata asks questions in the moment, exactly as they would in a classroom. Recordings are provided for revision only.

I joined the CS40+ course in January 2023, and it was completed within the mentioned time. I found the course very effective and well-organized. The teaching method and study material are up to the mark. I learned new things, and rather than mugging up the code, I learned to develop logic.

I had a really good learning experience with Kwickprep. The course was well-planned and taught in a very professional manner. The teaching style was engaging, and the study materials, especially for Python programming, were very helpful in understanding the subject better. All the concepts were explained clearly, and the teaching methods were easy to follow. I always received timely responses whenever I had a doubt, which made the learning process smooth and stress-free. I'm quite satisfied with the time I invested in this course. Overall, it was a valuable experience and helped strengthen my grasp on IP. Thank you, Kwickprep!
