    Why is the knowledge of the exam paper pattern important?

    The knowledge of B.E/B. Tech exam pattern of JEE Main is very crucial. You will be able to understand the weightage of each section and allot time accordingly. The Physics, Chemistry, and Mathematics sections have 25 questions each (20 MCQs and 5 NAT questions). Therefore, all three sections have an equal weightage and you will be required to dedicate an equal amount of time for each of them. Each subject has certain important chapters which you will have to focus on. Targeted study planning can be done according to the nature of the questions (MCQs and NAT). The paper pattern provides information regarding negative marking for incorrect MCQs. This knowledge will prevent you from making random guesses while attempting the paper. Familiarizing yourself with the paper pattern will also aid in attempting mock tests within the duration of 3 hours. Doing so will provide an insight into your capacity for time management in the actual examination.

    Why does JEE Main B.E/ B. Tech Get the Most Applications Out of All the Three Papers?

    Why does JEE Main B.E/ B. Tech Get the Most Applications Out of All the Three Papers?

    JEE Main B.E/B. Tech gets the most applications out of all three papers because it provides admissions to the top engineering colleges in India. Mainstream engineering is a choice of many students, leading to more applications as compared to the fewer numbers for architecture (B.Arch) and planning (B.Plan) courses. The number of best-ranking institutes taking in students through JEE Main Paper 1 is higher than those institutes taking students through Papers 2 and 3. On clearing JEE Main B.E/ B. Tech Paper, students will also have the opportunity to answer JEE Advanced for admission into IITs. Students have the option of taking JEE Main B.E/ B. Tech Paper in two sessions for better marks. All these factors contribute to the high number of applications for the JEE Main B.E/B.Tech paper.

    JEE Main B.E/ B. Tech Paper January 7, 2020 Shift II

    The afternoon shift timings were 2.30 PM to 5.30 PM. Once again, B.E/B. Tech paper was identified to be easier compared to JEE Main question papers of the previous year. 

    • In conceptual terms, physics was defined as the hardest section.

    • Mathematics was also high in terms of the level of difficulty and time-consuming at the same time.

    • As most of the questions were from NCERT in Chemistry, it was scaled easily by the candidates in terms of difficulty level.

    • The syllabus of Classes 11 and 12 was spread throughout the paper in a balanced manner.

    • Nevertheless, there were more questions in the mathematics section from the syllabus of Class 12.

    • Numeric value-based problems were difficult in physics and simple in chemistry. But attempting these questions in mathematics got difficult as the section was long and thus, time-consuming. 

    • Mathematics had 3-4 integration questions and they were all easy to attempt. Probability problems were also simple in maths. 

    • In this year's paper, the weightage of organic chemistry was more compared with last year whereas inorganic chemistry had only 2-3 questions. 

    • A few questions emerged from Newton 's law of cooling.

    JEE Main B.E/ B. Tech Paper January 8, 2020 Shift I 

    The question paper was considered to be of a moderate difficulty level with Mathematics being the most time-consuming section.

    • The numerical value-based questions from Mathematics were found to be easy by the candidates. However, many candidates suggest that test takers must save 90 minutes for the Mathematics section because attempting the desired number of questions will be challenging.

    • The question paper covered the syllabus of Classes 11 and 12.

    • For Physics, the Class 11 syllabus seemed to have more weightage. 

    • The Chemistry section which is usually easy in terms of difficulty level was tough this time. Candidates were not expecting a lot of questions from inorganic chemistry. However, there was a fair amount of questions from the topic. 

    • One question from Chemistry came from environmental chemistry regarding greenhouse gases. There were about 2-3 questions from ionization enthalpy.

    • The Mathematics section had questions from Matrix and Determinants, Arithmetic Progression, Vector and 3D, Parabola, Calculus, and Conic sections.

    Paper Attempting Tricks for B.E/ B. Tech Paper

    Paper Attempting Tricks for JEE Main B.E/ B. Tech Paper

    Trick 1 - Attempt the Chemistry section first, followed by Mathematics, and finally Physics. Chemistry is generally the easiest section and has more questions based on facts. The other two sections have more problem-solving questions. Mathematics is of moderate difficulty while Physics tends to be the toughest.

    Trick 2 - You could attempt all the NAT questions in the beginning because they do not have any negative marking. 

    Trick 3 - Find answers in terms of variables. This will eliminate the possibility of calculator mistakes and makes dimension checking very easy. 

    Trick 4 - Try to guess the order and dimension of each answer. This will help while rechecking your paper. 

    Trick 5 - Do not dedicate more than 5 minutes to one question. 

    Trick 6 - While attempting MCQs, reject the incorrect answers and then check the correct answer. 

    Trick 7 - Use the substitution technique for Physics and Mathematics. When unknowns such as x,y, or z are given in the question, consider them like 1,0, or any other appropriate digit relevant to the question. However, take care not to try this technique unnecessarily. 

    Trick 8 - If you have a quadratic equation question in the Mathematics section, first find the sum and product of the roots. Several questions can be solved with these two values. 

    Trick 9 - Check and recheck your calculations. 

    Trick 10 - If you are unsure about a question, move onto the next. This will help in time management. You can come back to the question at the end of the paper. 

    Trick 11 - The most important trick is to stay confident and positive.
