07:30 AM – 09:30 AM: Study Slot 1 — Core Technical Subject (theory + numerical problems).
10:00 AM – 12:00 PM: Study Slot 2 — General Awareness / General Studies (static GK, current affairs, OIL-related topics).

Best Books & Resources (Subject-wise)
Technical Subjects (Discipline-wise):
Refer to core textbooks from your branch (Mechanical, Electrical, Instrumentation, Civil, Chemical, etc.) used during graduation/diploma.
GATE standard books and handwritten notes are excellent for conceptual clarity and numerical problem practice.
Previous year question papers of OIL, ONGC, IOCL, BHEL, and other PSU exams for pattern understanding.

Energy/Oil Sector Awareness: OIL official website (latest projects & news), Ministry of Petroleum and Natural Gas website, annual reports, and India Year Book (Energy section).
Mock Test Strategy
Start Early: Begin with sectional mocks (technical, aptitude, reasoning) after covering 40–50% of syllabus.
Full-Length Mocks: Begin full-length mock tests 6–8 weeks before the exam. Attempt at least one per week initially, increasing to two in the final month.
Real Exam Simulation: Take mocks at the same time of day as the actual exam to condition your brain to peak performance during that time.
Mix Sources: Use a blend of coaching institute mock series, previous year papers, and self-made topic tests for variety.
Mock Test Analysis – Step-by-Step
Step 1 (Post-Test): Record time taken per section. Identify questions left unattempted and those guessed.
Step 2 (Error Log): Classify errors as Conceptual, Calculation, Reading mistake, or Time pressure. Maintain a separate notebook for these.
Step 3 (Root Cause): For each error, note the reason and corrective action (e.g., “Misread question → underline keywords next time”).
Step 4 (Targeted Practice): Reattempt similar question types the next day to reinforce learning.
Step 5 (Weekly Review): Review the error log every Sunday and track improvement in recurring weak areas.
Time Management During Exam
Sectional Allocation: Divide total exam time between Technical (major weightage) and Non-Technical parts. Attempt high-confidence technical questions first.
First Pass: Attempt all easy & confident questions quickly in the first 30–40 minutes.
Second Pass: Return to moderate/difficult questions; use elimination and approximation strategies.
Avoid Time Traps: If stuck beyond 1.5–2 minutes on one question, move ahead. Mark it for review.
Buffer Time: Keep last 10–15 minutes for reviewing marked questions and filling unattempted ones strategically.
Revision & Note-making Plan
Short Notes: Make concise notes for formulas, short tricks, and definitions. These will be vital in the last 2–3 weeks.
Flashcards: For technical definitions, GK facts, and vocabulary.
Revision Frequency: 1st revision within 48 hours, 2nd in 7 days, 3rd in 30 days using spaced repetition.
Current Affairs & Industry Awareness
Regularly follow Oil India Limited’s official website for new projects, MoUs, and updates.
Keep track of global oil prices, major discoveries in India, and new government policies in the energy sector.
Revise monthly current affairs compilations before the exam — focus on Energy, Science & Tech, Economy, and National Affairs.
Motivation & Health Tips

Exercise or go for a short walk daily to keep stress levels low.
Keep distractions (social media, unnecessary notifications) under control during study hours.
Set weekly goals and reward yourself for achieving them to maintain consistency.
Final 2–3 Weeks Strategy

Attempt 2–3 full-length mocks per week under strict timing conditions.
Revise one-page formula sheets and GK notes daily.
Keep calm, sleep well before the exam day, and trust your preparation.
