How To Prepare For GATE Environmental Science and Engineering?

Some students might have already started their preparation for GATE 2022, and some might be starting right now. No matter what category you lie under, these tips are for each one of you. But it is recommended that you must stick to tips from only a few sources. As they say, too many cooks spoil the broth. It’s better to stick to one source for both tips and study material. Read below to find out what are these tips. 

Don’t run

You read it right. Don’t run after completing the syllabus or mugging up as much as you can. Take it one at a time. You can start by preparing early so that you get a headstart. Take topics one at a time. Don’t hurry or you won’t learn anything.

Aim for accuracy

Your aim should be set on accuracy. It doesn’t matter if you learn 5 topics in a day or just 1. What matters is how well you have learned it. Your accuracy will influence your performance in the exam along with your speed. Don’t try to cover all the syllabus if you are short on time. Prepare for just 90 marks but prepare in such a way that those 90 marks are guaranteed. And trust yourself in the process. Have confidence in your preparation.

Basic and Standard

Learn basic concepts from standard books. Learning basic concepts is important as it will build your foundation and it should be strong. Approach standard books because the explanation of concepts in these books is simplistic and easy to understand. Your aim should be to gain concept clarity. That is possible when you are preparing from reliable and standard sources.

Follow a timetable

Being disciplined is necessary for everything you do. Especially during your preparation for any exam. Make a timetable in which you have to allot time to the topics according to your level of preparation. Discipline comes when you actually follow that table. Just making the timetable won’t do. Also keep enough leisure time so that it doesn’t get hectic.

Make Notes 

We have learned to make running notes since your highschool tie. Use that talent during your preparation. Make notes while you are doing a topic and go through it once at the end of the day. These notes should be to the point and precise. Keep them secured because they will be useful in our next tip. 

Do Revision

Imagine this, you have prepared the entire syllabus with all your dedication and in the last month, you sit to revise all of it. You find out that all you have learned has completely vanished out of your system. That’s a cue to panic. But you can avoid all of this if you just make it a habit to revise at the end of the day, whatever you have studied the entire day. Now you have revised the syllabus daily in small amounts. Now when you will sit in that last 1 month, it will all come back to you immediately. Also, you have revised the syllabus two times which is enough to score good marks. To revise, make sure to use those running notes that you made during your preparation

What is Environmental Science and Engineering ?

Environmental Science Engineering is a multidisciplinary field of engineering science that contains biological, chemical, and physical sciences with the field of engineering. This major traditionally requires the student to take basic engineering classes in fields such as thermodynamics, advanced math, computer modeling and simulation, and technical classes in subjects such as statics, mechanics, hydrology, and fluid dynamics. As the student progresses, the upper-division elective classes define a specific field of study for the student with a choice in a range of science, technology, and engineering-related classes

GATE 2022 Preparation FAQs

Q1. How many mock tests should I practice?
Ans. There is no specific number as such for solving mock tests. You can solve as many mocks as you can. Though you should practice them throughout your preparation. Try practicing from weekly mocks and topic-wise mocks.

Q2. Is the General Aptitude section important? 
Ans. Yes, the section is important as it carries 15 marks. If you prepare well then the section can be very scoring. 

Q3. How should I revise the entire syllabus?
Ans. You can make notes during preparation and then revise the syllabus from them. Also, you should revise in small parts so that you remember better.
