CSIR CDRI Technical & Technician Recruitment 2025 : Exam Preparation Strategy
- Start with the Official Syllabus
Don’t study randomly. CSIR’s syllabus is very defined. Print it and highlight topic-wise chapters. - Prioritize the Technical Subject
This carries the highest marks. 50–60% preparation time must be spent on the trade/subject. - Daily 3–4 Hours for Technical Topics Alone
Divide topics into: Basic → Intermediate → Advance → Application-based. - Give Reasoning 1 Hour Daily
CSIR reasoning is similar to SSC but slightly logic-heavy. - English Section Needs Regular Practice
Many candidates ignore this and lose 10–15 marks unnecessarily. - GK Should Focus More on Science & Research
CSIR labs, ISRO missions, DRDO news, Nobel prizes, important drugs—these matter. - Solve Previous Year CSIR TA/Technician Papers
Even solving 10–15 papers increases accuracy drastically. - Use PYQs of ISRO, DRDO CEPTAM, BARC Trades
These exams match 70–80% pattern similarity. - Make Short Notes for Formulas & Lab Techniques
Especially helpful for Chemistry, Biology, Engineering trades. - Practice Mock Tests Weekly
Increase frequency to 3 mocks per week in the last month. - Focus on Weak Areas First
Weak subjects take longer to improve—address them early. - Use Charts for Biological Pathways/Chemistry Reactions
Visual learning boosts memory retention. - For Technician Trades, Practice Hands-On Skills
Example: Electrical wiring diagrams, RAC cycles, lab equipment handling. - Time Management Practice
Technician exam is time-tight; accuracy + speed required. - Use Stopwatch for Reasoning & Quant
Helps maintain per-question time control. - Revise 5 Times Before Exam
CSIR papers are NOT tough but are memory-based. - Avoid Overloading New Topics in Last Week
Focus purely on revision + PYQs. - Sleep 7 Hours During Exam Week
Sleep boost improves memory, logical reasoning, and concentration. - Solve Questions Without Calculator
Technician/TA exams do not allow calculators. - Believe in Consistency
CSIR technical posts require stability. Even 2 hours of daily study for 2 months is enough for strong results.
