JEE MAIN 2018 NEWS

NATIONAL LEVEL ONLINE/OFFLINE TEST

The last 30 days countdown for JEE Main 2017 has begun and the board exams are also underway. Students therefore need to approach both JEE Main and boards with a compact preparation strategy to perform well. However, it is never easy to devise a full-fledged preparation plan for yourself. In this article, we will be looking at some of the key aspects that are crucial for JEE Main preparation and also go through out a weekly preparation plan for last 1 month.

**JEE Main 2017** is scheduled for April 02 (Pen & Paper based test) and April 08 & 09, 2017 (computer based test). All the engineering aspirants will appear in Paper I for admission to B. Tech and B.E. courses in NITs/IIITs/CFTIs/SFTIs and various state level institutes. Paper I consists of 3 sections namely Physics, Chemistry and Mathematics. The syllabus for JEE Main is based on class 12^{th} syllabus prescribed by CBSE. Candidates who are already focusing on boards’ preparation will definitely have a good starting point when they start preparing for IIT-JEE.

The total duration of JEE Main 2017 is 3 hours. In total 90 MCQs will be asked from 3 sections - Physics, Mathematics, and Chemistry. All the questions are distributed equally among the 3 sections. Each correct answer is awarded 4 marks while ¼ marks are deducted for every incorrect response. The distribution of questions from class 11^{th} and 12^{th} is mentioned below. Candidates have the option to attempt the paper in Hindi or English.

Subject | 11^{th} | 12^{th} | Total no. of questions |
---|---|---|---|

Physics | 12 | 18 | 30 |

Chemistry | 12 | 18 | 30 |

Mathematics | 12 | 18 | 30 |

With only 30 days left for the exam, you’ll have only 10 days to cover each subject – Mathematics, Physics, and Chemistry. Some of the important guidelines that candidates can keep in mind before they start preparing for **JEE Main** are mentioned below.

- Divide time equally to focus on preparation of all 3 subjects.
- Preparation for Mathematics go hand in hand with preparation for board exams, as you need to practice rigorously and solve as many questions as possible to score well in this section.
- Practice 2-3 mock tests every week. Take time to analyze your mistakes and learn from them.
- You should fix your daily hours for JEE Main preparation and try to get up early in the morning so that you have ample time at your disposal for preparation.
- Have a print out of your syllabus. You have no idea how helpful it can be.
- Avoid anything that is distracting you.
- Divide topics from each subject on the basis of their difficulty level:

- Hard
- Medium
- Easy

- Pick a hard chapter from one subject (Math, Physics or Chemistry) and an easy chapter from the remaining two subjects in your daily plan.

JEE Main 2017 Physics section consists of 30 questions. Current electricity is the most important chapter in terms of weightage. Given below are the important topics and the average number of questions asked in JEE Main Physics’ section in last 5 years.

- Study every single topic from NCERT and underline the important portions which you need to revise again in last few days.
- For Physical Chemistry, students are advised to solve all the previously asked JEE Main question papers because the questions are very frequently repeated from this topic.

JEE Main 2017 Mathematics section also consists of 30 questions. Coordinate Geometry is a very important topic in terms of weightage since almost 7 questions are asked from this topic. The average number of questions asked in JEE main Mathematics from various topics in last 5 years is depicted below.

Mathematics just requires rigorous practice. Early hours in the morning are usually good for practicing maths as it requires more brainstorming as compared to other subjects. Following are some of the tips for JEE Main 2017 Mathematics preparation:

- Students must make your Mathematics’ fundamentals strong. Maths’ syllabus has close to 15 chapters which students have covered over a period of 2 years. Mathematics is the only subject which can be perfected through practice only. Some Chemistry and Physics questions can be solved simply by formulas. But in case of Mathematics, practice is the only way forward.

- Start by noting important formulas from each chapter. Students might want to make flash cards. Whenever you can’t remember the formula, use flash cards.

Last, practice makes a man perfect. Try to solve questions that students usually find hard or of a higher level. Instead of solving 50 questions that you were able to do quickly, try to solve 20 questions that require extra brainstorming.

Reference books can go a long way in clearing all your doubts. Some of the best reference books available in the market for all the individual subjects/topics are listed below. Students do not need to buy all these books. Just one or two books would suffice.

**Chemistry**

Physical Chemistry is one of the most important topic. As discussed earlier in this article, students need to understand the core concepts of some important topics viz.

Some points to remember before starting the hard-core preparation of JEE Main 2017 are discussed below:

- Divide time slots in your daily plan to focus on all 3 subjects.
- Take short breaks after you finish each subject but not more than 30 minutes
- Stay hydrated and calm to cover all subjects.
- Don’t compromise on your sleep. (at least 6-8 hours of sleep)

**Week 1: Study Important & Less Important Topics in Mixed Format**

Try to study one important (or hard) topic of one subject daily and less important topics of the remaining two. Also, choose that subject which you find easy to study last. For example, in the table given below, the last time slot should be saved for Physics. However, some students might find Chemistry easy, then they can study it in the end**. **

Day | Mathematics | Chemistry | Physics |
---|---|---|---|

Day 1 | Logarithms Quadratic Equations Application & Derivation | Carbonyl Compounds Alkyl Halides & Aryl Halides Mole Concept | Work, Energy and Power Electrostatics Gravitation |

Day 6 | Probability & Statistics | Gaseous State Solid State | Newton’s Law of Motion Friction |

Day 7 | Attempt mock tests and sample question papers. While solving the mock test remember to note the time and try to end the test as soon as the allotted time is up. This will prepare you to manage your time properly on day of exam. After finishing the JEE Main Mock Test, go through the answers. Analyze your mistakes and revise those topics where you selected the incorrect responses. |

**Week 2: Start Revision of Previously Studied Chapters along with New Ones**

By week 2, students are already acquainted with the routine. Now they should revise the previous chapters too. As students may forget the previous subjects. Now a new mantra should be followed i.e., one less important (or easy) topic from one subject should be studied everyday and important (or hard) topics from the remaining two.

Day | Mathematics | Chemistry | Physics | Revision |
---|---|---|---|---|

Day 8 | Integration Differentiation | General Organic Chemistry Biomolecules | Simple Harmonic Motion Circular Motion | Wave & String Motion 3D Geometry Atomic Structure |

Day 14 | Solve the sample papers and mock tests. Time yourself and finish the examination within the allotted time. If you are still not able to finish the exam within the time limit, then work on your time management. Take note of the incorrect responses and go back to revise them. |

**Week 3: Give More Emphasis on Revision**

In week 3, revision should be the priority. Students usually forget to revise the chapters they have already studied and tend to forget the concepts

Day 28 | Solve subject wise sample question papers and mock test. Make sure all the important topics studied in this week are covered. Since the JEE Main exam is near, spend the entire day fixing the incorrect responses and trying to understand those concepts which you find hard to grasp. |

Day | Things to Do |
---|---|

Day 29 | Take a look back at all the notes that you have made while preparing for the examination. Decide upon your strong and weak points in the syllabus Go back and have a look at the concepts and topics you are still unsure of. Try to understand and learn the basic concepts. |

Day 30 | Make flash cards and revise and learn through them. Revise all of the formulas learned till now. Assign each concept or formula with a keyword with which you can easily relate and remember. |

Day 31 | Look at the topics you are most confident in and revise it. Knowing your best known topics in more detail will allow you more scope to score more in the examination DO NOT STUDY ANY NEW TOPICS. Just keep revising all that you have studied and do not pick any new topics. Strengthen concepts which you have already studied. |
