Preparing for GATE Chemical Engineering is not an easy task and if you are going with self preparation it needs a lot of discipline. There is a lot of confusion about where to start and what to read. There is always a way out of this confusion and that is what this section is all about. Read the following articles to get an idea…
Early Revision Technique
There is no substitute for early revision. You need to start early.
You really want to give yourself sufficient time to revise all that you have contemplated and ensure that you grasp it. Last moment revision is considered useless. Revise each subject as you go, and ensure that you revise it completely as this will make modification a lot more straightforward. Eventually, the best tip is to focus on and know your syllabus, and beginning early is the most effective way to accomplish this.
Vary your revision techniques
Continuously revising, for example, reading your notes regarding a topic, is probably going to be very dull. Brighten up your revision period by revising various topics and methods.
Practice old question papers
Doing revision on previous papers will test your comprehension skills. Revise all previous year’s papers as much as you can.
Draw maps and keep techniques
Drawing mind maps or other synopsis charts to test what you can revise, and afterward, really look at them on your notes. Notice where you have left out a detail or where you forgot.
Take Regular breaks in between study schedule
Take regular breaks and don’t study continuously for hours. Basically, it is very hard to study for more than half an hour and keep concentrated.
Find those days when you can do more and utilize that day. self-preparation
