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 both the books below.
I have listed them in order by my preference.That is you should buy first book.If for some reason you do not then you can buy the second book.
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.
The syllabus presented below is taken from official website of GATE exams (link).So the syllabus is latest and authentic.

One thing is worth mentioning here is that we have not covered Engineering Mathematics much in our online test series.Focus in more on other sections.As bulk of questions are from other sections we have decided to take this route.You can also post your questions about online tests or in case of any help or suggestion.
