GATE Environmental Science and Engineering (ES) 2023 Preparation
GATE ES 2023 Preparation Tips
GATE assesses the candidates on their ability to Recall, Comprehend, Apply, Analyse and Synthesise the concepts and knowledge. Keeping these parameters in mind, candidates must create their own personalised study strategy and follow the same diligently. However, to get started students can check the preparation tips discussed below and improvise wherever necessary. Finally, in order to score well in GATE ES 2023, students just require determination, diligence and discipline.
- Syllabus: Go through your syllabus carefully, identify your weak and strong topics and understand the marking scheme. Try bifurcating the syllabus based on the marks and difficulty and start your preparation from there.
- Scheduling: Start as early as possible, GATE will require a thorough preparation and thorough preparation requires ample time, hence, starting early will give a head start, extra time to brush up on concepts that feel hazy. Distribute the topics to be covered each day.
- Short Notes: Cultivate a habit of making short notes while covering a topic, this will help you during your revision and will work as the last minute study prep.
- Resources: Rather than gathering loads of study materials and resources, gather the most relevant ones and those that cover the topics from the GATE Exam point of view. Keep your engineering books close for quick topic reference.
- Question Papers and Mock Test: Solve a ton of Previous Year Question Papers, Sample Question Papers and appear for Mock Tests. These are necessary, not just for the preparation of the GATE but also to give you an exam temperament and avoid unnecessary stress.
- Relax: Relaxing is as underrated as it gets. While preparing for an exam such as GATE ES 2023, building up stress and tension is common. Practice a few recreational activities such as listening to music, yoga, exercise, a simple walk etc., to blow off some steam. A calm mind can perform well compared to a stressed mind.
