Vocational Group: Office, Spreadsheet, Web and E-Commerce Skills

What this domain tests

The Vocational Group syllabus tests employable computer application skills: office automation, spreadsheet accounting, desktop publishing, web page design, e-commerce and digital payments, and cyber safety. Questions are task-based and reward exact procedures rather than general definitions.

Core rules to keep straight

  • Word processing: use heading styles for structure; mail merge combines a main document with a data source, so verify fields before merging.
  • Spreadsheet functions: =SUM(B2:B10), =AVERAGE(B2:B10), =IF(condition, true_value, false_value). Use absolute references for fixed rates such as tax or discount.
  • DTP: distinguish margins, bleed, resolution and colour mode; vector graphics scale without pixelation, raster images do not.
  • HTML: use html, head and body structure; heading tags h1–h6; links with href; images with alt text; close elements correctly.
  • E-commerce: an invoice carries seller details, GSTIN, item description, quantity, rate and tax; payment gateways must never ask for card PIN or OTP in chat.

Worked example

A worksheet stores quantity in B2, rate in C2 and a discount rate in E1 (10%). The formula =B2C2(1-$E$1) gives 42500.90 = 900 when B2=4 and C2=250. The $E$1 lock is essential: copying the formula down keeps the discount cell fixed, while a relative E1 would shift to E2 and break the calculation.

Traps that cost marks

  • Entering numbers with spaces or commas so the spreadsheet stores them as text and SUM ignores them.
  • Using a relative reference for a fixed tax or discount rate.
  • Running mail merge without refreshing or checking the data source.
  • Leaving HTML tags unclosed or attributes unquoted.
  • Sharing OTP, PIN or CVV in digital payment tasks.
