How to Prepare for GATE Metallurgical Engineering?

Your preparation depends on your strategy. If it is not well thought then you might lose marks in the exam. Your strategy should tackle your preparation in such a way that you are able to cover all the topics. Your strategy should also divide topics from easy to difficult, less to more weightage, or less to more important. Then prepare for subjects according to your comfort. The last month should be kept for revision. Candidates can look for the tips that we have mentioned below for their preparation. 

Exam Syllabus

Candidates must go through the syllabus thoroughly. They should be familiar with each topic in the syllabus. Divide the topics and prepare them accordingly. You should also go through the exam pattern and the marking scheme of the exam. Through the exam pattern, you will know what sections you have to prepare for. All three – the exam pattern, marking scheme and the syllabus are important in the preparation of the GATE 2021 exam and you should know them well. 

Basic concepts

The understanding of basic concepts is really important. You should have concept clarity in all the topics. This will help you in preparing better for the exam. Don’t move on to any other topic unless you are through with the topics you have been preparing. Understand them well and keep practicing them simultaneously. If you gain concept clarity you will be able to solve even the difficult questions which will make it easier for you to score in the exam.

Preparation notes

You must make it a habit to make notes during your preparation. Notes should be made for every single topic in your GATE 2021 syllabus. The point of making the notes is to understand the topic first and then write it by hand. If you have understood the concept, only then will you be able to create notes. This technique helps in memorizing the topics well. Also, these notes will come in handy when you are revising the entire syllabus. 

Solve papers

Your preparation should be done through solving as many question papers as you can. Start with your weekly and monthly mock tests. It will help you in keeping track of your weekly and monthly progress. As you near the last two months, start taking full-length mocks. Also, solve at least 10-15 last years’ question papers. This will help you in getting familiar with the trend of the questions that have been followed over the past few years. 

Revision

As you start getting near the last month, start revising the syllabus. Take the help of the notes that you made during the preparation. Revision is an important step or you will forget what you have learned so far. Also, do daily revision, this way you will remember better. 

Books for GATE MT Preparation 

Candidates are suggested to prepare for GATE 2021 from the best material only. The sign for good material is the renowned author or the publication of that material. Your material should be limited and of good quality.
