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 ISC Class 12 Computer Science (with Java) (CS) covers
The course follows the full syllabus, 13 units.
- Boolean Algebra
Propositional logic, well-formed formulae, truth tables and interpretation; Satisfiable, unsatisfiable and valid formulae; Binary-valued quantities; AND, OR, NOT operations and equivalence laws; Basic theorems: duality, idempotence, commutativity, associativity, distributivity - Computer Hardware
Elementary logic gates: NOT, AND, OR, NAND, NOR, XOR, XNOR; Universal gates (NAND, NOR) and circuit applications; Half adder and full adder; Encoders, decoders and multiplexers using Boolean algebra - Implementation (Algorithms to Programs)
From algorithms to working Java programs; Programming environment (BlueJ, JDK); Review of Class XI Java concepts - Objects and Classes
Objects as attributes (state) and behaviour (methods); Object as an instance of a class; Constructors: default, parameterized and copy constructors; Static members and static methods - Primitive Values, Wrapper Classes, Types and Casting
Primitive types: int, short, long, float, double, boolean, char; Wrapper classes and autoboxing/unboxing; User-defined types via classes; Type conversion, coercion and casting - Variables and Expressions

Students from around Kolkata
A student anywhere in Kolkata can take ISC Class 12 Computer Science (with Java) (CS) 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.

Shubhranshu enjoyed the classes with Kajal Mam as she taught really well. She kept him engaged even in online classes. He joined the classes just few months before exams and still managed to score well as Kajal Mam taught him strategically and continuously. Hats off to her hard work and perseverance.
