Chemical Engineering is one of the papers in GATE Exams.In this article I will provide you materials required to crack this paper with ease.I will cover below topics in this article

- Paper Statistics
- Free Online Test
- Recommended Books
- Detailed Syllabus
- Free Android App

I have written separate article on GATE Exams. In case you are not aware about the exam details or want to know it in details then read my post.It covers everything you need to know before appearing for exam.It covers eligibility criteria, exam format and other important information.You can also post your questions if any there.

## GATE Chemical Engineering Statistics

Below are some interesting Statistics about GATE Chemical Engineering paper

- Number of candidates registered for the exam – 19,000 (approx)
- Number of candidates appeared for the exam – 15,000 (approx)
- Number of qualified candidates – 3317
- Percentage of candidates qualified – 20% (approx)
- Maximum marks out of 100 – 83
- Minimum marks out of 100 – 22
- Average marks – 39.59
- Standard Deviation – 9.55

The pass percentage of Chemical Engineering paper is in line with most of the GATE papers. On an average most GATE papers have pass percentage of 20. So complexity wise it is in line with other papers.The average marks is about 40 with maximum marks being 83 and minimum being 22.

So majority o candidates have marks in range of 30 to 50.The average marks is close to minimum marks.So concentration of marks is on lower side. Candidates scoring above 55 will have decent ranks based on above statistics. I gave above statistics to give you an idea of results.

It is important to know average marks. You should always try to score more than the average marks. If you outscore average marks by 10 then you will have fair chances of good ranking.This information helps in planning and preparation.You should plan to score more than 60 and based on that target select the topics.

Below materials will help you in your preparation.

## GATE Chemical Engineering online tests

GATE exams have two different exams for students of Chemistry background.One examination is Chemical Engineering and other one is Chemistry.In this post we will discuss about Chemical Engineering.I will also outline the syllabus of Chemical Engineering later in this post as well.

Below are list of online tests prepared with upcoming GATE Chemical Engineering paper in mind.You can try the online tests to supplement your preparations.It is advised to attempt all online tests.You should also remember and understand the questions.Some questions are from previous year GATE exams as well.

Instead of creating too many tests with repeated questions we focused on quality. All the tests are unique and important questions for upcoming GATE exams were selected.The aim was to give best preparation material to candidates.

## GATE Chemical Engineering recommended books

There are many books in market on GATE Chemical Engineering paper.Out of those books I have selected these two books.These two books have positive reviews by candidates.Students have found it useful while preparing.I have listed the books below.

The present GATE tutor for GATE Chemical Engineering has been divided into three sections namely General Aptitude, Engineering Mathematics and Chemical Engineering, each sub-divided into number of chapters. The chapters cover unit wise and topic wise collection of theory and question answers.

Each chapter in the book contains ample number of solved problems which have been designed on the lines of questions asked in previous years GATE Chemical Engineering.The exercises contain questions as per the GATE pattern i. e. 1 mark questions, 2 marks questions and common data and linked answer questions.

The books contain Unitwise Numerical Answer Type Questions and newly added topics in questions. The book also contains last six years solved papers of original online GATE Chemical Engineering to give the aspirants an insight into the trends of questions asked in GATE Examination. The book comes with a free CD containing Online Mock Tests.

You can buy the book in discounted price using below link

## GATE Chemical Engineering syllabus

You should refer syllabus while preparation.Instead of reading everything out of order you should read in order given below.The chances of reading in syllabus order helps you.You will know topics you covered and topics pending.This in turn helps in better planning.You will not miss out on important topics as well.
