How to prepare for IES?
- ESE written exam consists of both objective and conventional type questions hence theory, conceptual knowledge and problem solving techniques are equally important.
- Good writing skills, excellent presentation, subjective theory, explanations, derivations, diagrams and equations will fetch you good marks in conventional or subjective paper.
- Be aware of exam pattern like how many technical & non-technical questions are asked, negative marks, weightage, exam duration and marks per question. Always make a habit of referring previous year question papers.
- Prefer Reference books for derivations, equations, conceptual thinking, theory etc.
- Short Cut Techniques: Use short techniques for numerical solving instead of traditional approach.
- Reading news paper, watching morning bulletin, surfing websites will help the candidates to prepare and score better in the General ability paper carrying 200 marks. Do not neglect General Ability part as this section is scoring and also plays an important role in personal interview.
- Practice previous year question papers and analyze the weak topics and concentrate more on those topics. Always try to solve the papers in given time to obtain an idea that how many questions you are able to solve in given time limits.
