Maharashtra HSC Computer Science (Bifocal) study plan

Convert 20 numbers between binary, octal, decimal and hexadecimal without a calculator, showing each step

Write and trace 10 small C/C++ programs that use if-else, switch and nested conditions, predicting output before running

Represent 8 negative decimal values in 8-bit 1's and 2's complement and state the range of signed 8-bit integers

Build a one-page handwritten cheat sheet of number-system conversion shortcuts and operator precedence

Write 12 loop programs (sum, factorial, prime check, digit reversal, pattern printing) and dry-run each on paper

Implement 5 user-defined functions with call-by-value and call-by-reference, and explain the difference in one line each

Describe the stored-program CPU cycle (fetch-decode-execute) and map each stage to the registers involved

Draw and label the memory hierarchy from registers to secondary storage, noting relative speed and cost per bit

Solve 10 truth-table and basic Boolean-simplification problems using AND, OR, NOT, NAND and NOR

Implement 6 array programs (search, sort, reverse, matrix addition) in C/C++ and state the time cost of each loop structure

Write 3 recursive functions (factorial, Fibonacci, sum of digits) and trace the call stack for n=4

Build a stack and a queue using arrays with push/pop and enqueue/dequeue, then show one overflow and one underflow case

Compare array and linked list on insertion, deletion and search in a short written table

Explain linear vs binary search with a worked 8-element example of each

Write 15 SQL statements covering CREATE TABLE with primary and foreign keys, INSERT, UPDATE, DELETE and SELECT with WHERE, ORDER BY and GROUP BY

Write 8 queries using INNER JOIN, and one each of LEFT JOIN and a subquery with IN

Normalise one messy student-marks table to 1NF, 2NF and 3NF, writing the reason for each split

Write C++ file-handling programs that write 10 records to a text file and read them back with getline and eof

State the difference between DDL, DML and DCL with one example command for each

Draw and compare star, ring, bus and mesh topologies with a one-line advantage and drawback for each

Explain the OSI seven layers and map TCP/IP layers onto them, naming one protocol and one device per layer

Solve 10 IPv4 problems: identify class, default mask, network and broadcast address for a given address

Contrast circuit, packet and message switching, and describe what DNS, HTTP and SMTP each do in one sentence

List the main functions of an OS (process, memory, file, device management) and distinguish multiprogramming from multitasking

Build a 4-page static HTML site (home, about, gallery, contact) using headings, lists, tables, images and links, with all tags closed correctly

Create a working HTML form with text, password, radio, checkbox, select, textarea and submit inputs, and label each control

Explain the file allocation methods (contiguous, linked, indexed) and directory structures with a small diagram

Describe absolute vs relative paths and write 6 correct relative links between your own pages

Write out 10 HTML tag definitions from memory and verify them against your own page source

Compare waterfall, spiral, prototype and iterative SDLC models in a table of phases, strengths, weaknesses and suitable project type

Write a one-page SRS for a library management system containing at least 8 numbered functional requirements

Explain black-box vs white-box testing and write 5 test cases with input, expected output and actual result for your own earlier program

Describe the roles of the feasibility study, system analyst and documentation in the SDLC, one paragraph each

Re-solve 10 previously wrong questions from Domains 1 and 3 and log the error cause for each

Complete two full-length timed mock papers covering all eight domains and score each against the marking scheme

Redo every question missed in the mocks until you can solve it without notes, tracking the score change

Recite from memory the key definitions for all eight domains using your own condensed sheets

Practise 15 SQL queries and 10 C/C++ output-prediction questions under a 25-minute timer
