Hello Raghavendra,

It is good that your participating in Gate exam as you have asked about the Test Series this is one of the best query regarding Gate exam because, most of them fail in selecting the best test series. Remember you shouldn't compromise with the question paper standard in test series because, the tough questions improves and builds your thought process over the given concept.

So I'll suggest you to select 2 to 3 test series to improve your confidence as well as way solving. The test series are :

1) ACE ACADEMY

2) GATE ACADEMY

3) MADE EASY use these test series atleast for the Aptitude and Mathematics.

And for your core XE paper you can appear for below 2 test series:

1) Grade up (Test series & mock tests)

2) Endurance Engineering Academy

Still many more are there but I think these test series are best for you to practice and achieve a good rank.

Hope you have no doubts regarding your query.

Hello there

See, each and every chapter is important is important in JEE syllabus.And the chapter you mentioned is Heat and Thermodynamics is one of the most important topics including

sound and waves , electricity,magnetism etc..

Candidates most often think Heat and Thermodynamics as toughest part but with practice and understanding it will be clear .

According to JEE MAIN 2021 ,these are the most important topics and chapters of Physics  ;

*THERMODYNAMICS

*ELECTROSTATICS

*ROTATIONAL MOTION

*SHM

*MAGNETISM

*MODERN PHYSICS

*OPTICS

Here are some book recommendations ,you can follow ;

•NCERT CLASS 11 AND 12 TEXTBOOKS

•CONCEPTS OF PHYSICS BY HC VERMA (BOTH THE VOLUME)

•PROBLEMS IN GENERAL PHYSICS BY I.E IRODOV

•FUNDAMENTALS OF PHYSICS BY HALLIDAY,RESNICK & WALKER

You can also visit the link for preperation tips ;

Some of the most preferred books for the subject are:

• Chemical Engineering Thermodynamics  by Gavhane
• Introduction to Chemical engineering Thermodynamics by Smith and Ness
• Introductory Chemical Engineering Thermodynamics by Eliott

You may search this books on Pdfdrive or Libgen for the pdf versions.

I hope this answer helps you. All the very best for your future endeavors!

Hi Candidate,

Hybridization in Central carbon atom refers to the number of Sigma- bonded groups attached to the main center. The hybridization in the carbon group is- ((CH3)3).C where the outer "C", is the central carbon atom. The central carbon atom is tied to three CH3 and one Hydrogen atom, which makes it sp3 Hybridization.

Hope that this answer helps you. Have a Good Day!!

Hello candidate,

Covalent bonding is a very strong kind of chemical bond apart from ionic bonds which are formed by by the donation and acceptance of electrons. In covalent bonding, the electrons of of both the participating atoms get paired with the electrons to form a bond.

The cleavage of chemical bond is generally done by the process of heating the molecules up to their bond dissociation energy, which involves a huge amount of exothermic heat generation.

Hope it helps!!

Hey student,

I hope you are doing good.

I hope it helps.

Dear Student,

The word Electrophile, is made up of two words. The one is Electro which means electron and the second word is Phile which means liking/loving. Overall the word Electrophile refers to the species which likes electrons. By this , we means that, in a chemical reaction the electrophile species gets attracted towards an electron. Hence an Electrophile should be regarded as an Electron liking/Loving species.

Hope this helps.

Hello Sangita Kumari!

Before getting into the exact answer, a few things to say!

1. Mechanics is the basics of physics. It includes linear motion, laws of motion, rotational motion etc. It is not related to electricity or optics.
2. I would recommend you to study optics and then waves. because some of the basic concepts of optics such as wavelength, frequency etc also appear in waves. You can also simultaneously study them if that is comfortable for you.
3. Then for electricity part, electrostatic is the basic chapter and a proper understanding of it will help current electricity chapter.
4. Then you can study Magnetism and electromagnetic induction.
5. Thermodynamics can be covered in between.

So I would the sequence mechanics, electrostatic, current, magnetism, electromagnetic induction, thermodynamics, optics and waves.

Note that this is my opinion. I f you feel any other sequence comfortable go with that. Remember that while you are covering a new chapter you must regularly revise the previous chapters.

All the best!

Hello there

You have given me a really tough job though as no one can predict that from which sections jee advanced gives more questions .

Okey for chemistry if you have left the physical chemistry then you will still be able to  clear the cutoff for chemistry ( you must know that you have to score a minimum marks in each subject individually ) for maths portion the portion you have told is quite less .The calculus part carries a lot of marks so can't be left in order to get qualified .

For physics ,jee advanced usually prepares questions which caries concepts from multiple chapters so you must know the theory of most of the chapters ,however you can avoid doing much questions

Practice wisely and be consistent and keep working hard

Best wishes
