After important topics from each section, now turn your focus towards some of the important tips from each subject in order to score high marks in the JEE Main 2019. We are discussing some of the crucial tips for you below:
Mathematics
 In Coordinate Geometry topic, do not try to solve equations. In order to save your time, just put the given options in the equation and check what fits best.
 In problems related to Integration, just differentiate the given options and find out the correct option.
 Similarly, in the topic of Differentiation, integrate the given options and check the appropriate option.
 In Algebra, look at the options carefully to see which one has an anomaly related to the property. In 99% questions, the option with the anomaly will be the right option.
 In Quadratic Equations, 90% questions are based on properties of alpha, beta and gamma in which you have to find the sum of roots or the product of roots. For these questions, know the properties well and the rules that required to solve such questions.
 Problems based on Complex Numbers, read the question carefully to check out if the answer would be an imaginary number or a real number. Eliminate the choices that don’t fit first and then, try to check the question with the correct answer.
Physics
 The quickest and simplest way to solve a Physics question is to read the question carefully and find out what should be the exact unit of the answer.
 The Optics related questions mostly have only onestep solutions. For this, you can compare options with the given question and find easily which one would be the correct option.
 Electricity related questions are mostly propertybased. Read them carefully and find out which is the only one or at the most two options that satisfy the property in question.
Chemistry
 Periodic Table questions are undoubtedly based on the properties of the elements. Learn the periodic table to surely score that marks.
 Thermodynamics is a common topic in both the subjects Physics and Chemistry. Thermodynamics question asked in one subject is usually based on the same concept as asked in another subject, with the opposite logic. The same logic is applicable in Nuclear Physics and Nuclear Chemistry.
 4550% questions in Chemistry are from Organic Chemistry. Hence, remember all the reactions. Compare options with the reactions; only one or two are relevant.
 Physical Chemistry questions are always numerical, connected with questions on Electrochemistry.
The success in JEE Main 2019 is tough to earn and you are just one step away from that. So, keep all the important tips and strategies in your mind for JEE Main to achieve that sureshot success in JEE Main 2019.
