Plus Two Computer Science — How to Prepare for Theory and Practicals

Plus Two Computer Science mixes programming, web technology and databases. It is a very scoring subject because most questions test clear concepts and short programs, and a big share of the marks comes from the practical exam.

This guide explains how the subject is assessed and how to prepare each part.

How Computer Science is assessed

The written paper has 60 marks, and 40 marks come from the practical exam and continuous evaluation (CE) together.
You need at least 30% in the written paper (18 of 60) as well as the overall minimum, so practical marks cannot carry a weak theory paper.
Questions range from one-word and short answers to programs and longer explanations. Use your SCERT textbook and the teacher’s notes as the main material.
Students in Commerce or Humanities who take Computer Applications can use the same approach; check that subject’s scheme with your school.

Programming (C++)

Learn the syntax of each topic (such as structures, pointers and object-oriented ideas like classes and objects) with one short example each.
Practise writing programs by hand, not only on the computer: in the exam you write them on paper, so small syntax errors cost marks.
For theory questions, define the concept, give one example and, where useful, a short code fragment.

Web technology and databases

HTML: learn the common tags and their attributes; practise writing a small page with lists, tables and forms.
JavaScript and PHP: learn basic syntax, simple programs and the difference between client-side and server-side scripting.
Databases and SQL: learn the key terms (keys, tables, relations) and practise SQL commands for creating tables, inserting, selecting with conditions, updating and deleting.
Make a one-page sheet of tags, commands and their uses for quick revision.

The practical exam

Practise every program in your record until you can write and run it without help, and keep the record book complete.
In the exam, write the program neatly on paper first if required, then type, run and test it with sample input.
Revise viva questions: definitions, the purpose of each program and common errors.

A revision plan until March

Now to December: one program a day by hand, and a tag/command sheet as you finish each chapter.
January–February: practicals and model exam; revise theory chapter by chapter and solve previous papers.
The last weeks: your sheets, record programs and previous-paper questions every day.
