Data Insight: Students who concentrate on high-yield areas usually get 10-15 percent more than those students who do not.
Solution: Top-weightage subjects will have to be scheduled, followed by a concentration plan on those topics. The entire core subject and specific problem practice will require dedicated time to build up the student's confidence in answering these questions.

Neglecting Engineering Mathematics and General Aptitude

Suggested Article: Importance of Engineering Mathematics in GATE PE

Mistake: Often candidates pay attention only to technical areas and underestimate the importance given by the institute to Engineering Mathematics and General Aptitude. Both of these together cover 15% of total marks.
Data Insight: GATE scores indicate that the overall score can increase by 10-20% when scores in these sections are well above the average, often making all the difference between qualifiers and top scorers.
Solution: Set apart at least 2-3 hours a week to practice mathematics and aptitude questions. It is easy to get maximum marks from the scoring sections like calculus, linear algebra, and logical reasoning.

Lack of Revision and Formula Memorization

Mistake: With a voluminous syllabus, most students overlook periodic revision, particularly about crucial formulas, leading to poor recall during an examination.
Data Insight: On average, candidates who train regularly score 15% higher since they remember and apply the formulas better to complex numerical problems.
Solution: Keep a separate formula book and revise only during the last 1-2 weeks. Use flashcards or summary notes to recall formulas and keep practicing applications to better retain the formulas.

Relying Solely on Theory without Practical Problem-Solving

Mistake: Students are overly concerned with the theoretical understanding and, in fact fail to apply that to real problems, which make up a majority of GATE PE.
Data Insight: Over 60% of the GATE Petroleum Engineering questions are application-based, which demands a mix of theory and problem-solving. Candidates who are weak in practice often lose marks because of time constraints or wrong application of concepts.
Solution: Balance theoretical study with problem-solving. The moment you finish discussing a concept, attempt practice questions on that concept. Make sure you attempt at least 20 practice problems every week from high-weightage topics.

Ignoring Time Management and Exam Strategy

Mistake: Most candidates tend to make a mistake in not taking seriously the aspect of time management. Either they spend too much time on the challenging questions or they fail to complete the paper within the allocated time.
Data Insight: For the student in GATE PE, where he is expected to answer 65 questions in merely 180 minutes, the time will become the crucial factor determining his success. Students so trained in time management finish the paper that much more efficiently and are about 15-20 percent more efficient.
Solution: You use practice exams to develop your strategy for time management. Make sure you set times for sections and prioritize quick-solvable questions. It is advisable to move on from overly challenging questions if you have extra time later to come back to them.
