Atomic structure is an important topic from JEE point of view. It is considered to be one of the easiest topics in JEE chemistry. It is more about formula application. Hence, you are expected to memorize all the formulae and practice their application.

This chapter is merely an extension of motion in one dimension. Students should realize that motion in two dimensions can be broken down into two independent one dimensional motions. The resultant motion is superposition of these two independent motions.

Have you also ever "dreamt" of being in one of the most premier institutes of India - the IITs? If your answer to the above question is a big "YES", I am glad to meet you here on this blog! I am Harshita Srivastava, a second year undergraduate student at Indian Institute of Technology, Kanpur.

Coordinate geometry has always occupied an important and major part of JEE question paper each year. Considering the weightage analysis for JEE mathematics of past few years, coordinate geometry (2-D) has been found to have occupied approximately 20% of JEE mathematics question paper each year. 

Graduate Aptitude Test in Engineering (GATE) is one of the toughest examinations for engineering graduates in India that primarily tests the aptitude of engineering graduates in solving the engineering problems. 

This chapter in itself is a combination of many other chapters. Although rarely direct questions are asked from this chapter, yet it finds endless applications in calculus and algebra, so basically it serves as a “tool” to solve problems of other topics.

Negative marking and extensive competition in Graduate Aptitude Test in Engineering (GATE) make it one of the toughest examinations in India at graduate level. There is no limit in the number of attempts in GATE. However, a failure attempt means, loss of one year of life and career. 

JEE syllabus covers the following concepts in quadratic equations and expressions:

• Quadratic equations with real coefficients
• Relations between roots and coefficients
• Formation of quadratic equations with given roots
• Symmetric functions of roots.

This topic is the very first lesson taught in chemistry. It introduces the students with the most fundamental but most important tools of chemistry – mole concept and stoichiometry. There are other basic concepts and definitions involved which serve as tools for a chemistry student to solve the concerned problem.
