If you’re wondering which books to study, start with trusted books that cover the complete ISRO Assistant, JPA, UDC & Stenographer syllabus. Reading from the right resources saves time, improves understanding, and makes revision easier as the exam approaches.
ISRO 2026 Subject-Wise Study Material & Preparation Strategy
1. General English / English Language & Comprehension
This section tests grammar, vocabulary, and comprehension ability. Focus areas include:
- Reading comprehension passages
- Error detection and sentence correction
- Idioms, phrases, and one-word substitutions
- Synonyms, antonyms, and vocabulary building
- Cloze test and para jumbles
Preparation tip: Since JPA/Stenographer candidates face 100 questions in this section (double that of Assistant/UDC), daily comprehension practice and a strong vocabulary base are essential. Reading English newspapers daily and solving previous years’ bank/SSC-level English papers builds speed and accuracy.
2. Quantitative Aptitude
Covers Number System, Percentages, Profit & Loss, Ratio & Proportion, Time & Work, Time & Distance, Simple & Compound Interest, Mensuration, Trigonometry, Algebra, and Data Interpretation.
Preparation tip: Build a formula sheet for each topic and practice speed calculation techniques (squares, cubes, percentage-to-fraction conversions) since the 150-minute window is shared across all sections. Data Interpretation and Simplification questions are usually scoring if practiced regularly with time-bound mock tests.
3. General Intelligence & Reasoning Ability
Includes both verbal and non-verbal reasoning: Series, Analogy, Coding-Decoding, Venn Diagrams, Sitting/Ranking Arrangement, Blood Relations, Direction Sense, Calendar, Clock, Mirror & Water Images, Dice and Cube problems.
Preparation tip: This section rewards pattern recognition, so solving a mix of puzzle-based and figure-based questions daily helps. Time yourself on arrangement and series-based sets, as these tend to be the most time-consuming.
4. General Knowledge
Covers current affairs (national and international), history, geography, polity, economy, science, and culture — with special relevance to space science and ISRO’s own achievements given the recruiting body.
Preparation tip: Maintain a monthly current affairs revision routine and specifically cover recent ISRO missions, space policy updates, and government schemes, since GK questions in PSU/government exams often carry organisation-specific relevance.
ISRO Skill Test 2026: Computer Literacy Test Syllabus
All shortlisted candidates (Assistant, UDC, JPA, Stenographer) must clear a Computer Literacy Test of 75 minutes duration, covering:
| Module | Marks | Key Topics |
|---|---|---|
| MS Word | 35 | Formatting, tables, mail merge, page setup, tracking changes, shortcut keys |
| MS Excel | 35 | Formulas, spreadsheet addressing, sorting/filtering, charts, validation |
| MS PowerPoint | 30 | Slide layouts, formatting, inserting graphics, headers/footers |
Passing criteria: 60% for UR category, 50% for reserved categories.
Preparation tip: Hands-on daily practice on an actual computer — not just theory — is critical here. Practice creating tables in Word, using VLOOKUP/SUM/AVERAGE formulas in Excel, and building a basic slide deck in PowerPoint under timed conditions.
ISRO Stenography Skill Test 2026 (For JPA & Stenographer Posts)
- Shorthand dictation: 300 words at 60 words per minute (5 minutes)
- Transcription on computer: 30 minutes
- Must follow Pitman’s shorthand system (longhand not permitted)
- Pass criteria: Maximum 10% mistakes for UR, 12% for reserved categories
Preparation tip: Regular timed dictation practice at 60 wpm using Pitman’s shorthand, followed by immediate transcription drills, is the most effective way to build both speed and accuracy simultaneously. Reviewing common error patterns (omissions, substitutions, spelling errors) from practice transcripts helps track improvement.
