JEE 2019 or Joint Entrance Examination is a national level engineering entrance examination conducted at the undergraduate level for granting admission to various BE or B.Tech courses offered by 23 IITs, 31 NITs, 23 IIITs, and several GFTIs (Government Funded Technical Institutes). Apart from this, the students will be granted admissions to other government and private technical institutes based on the marks scored in IIT JEE 2019. The examination is conducted in two phases known as Mains and Advanced. Acceptance in IIT or NIT colleges is the dream destination of almost all the students with engineering bent of mind. It is one of the most prestigious examinations which draws the attention of lakhs of students. Every year around 1.4 million students prepare for this exam of which less than 1% of students fulfil their dream of pursuing higher education in the top engineering institutes in India. IIT JEE is tough to crack because of its paper pattern and enormous syllabus including 2 years of study material. However, it’s not a hard nut to crack. Smart preparation strategy, practice, regular revision and proper guidance can assure a meritorious position in IIT JEE 2019.

Occupying a seat in top engineering institutes like IITs, NITs is probably the first step towards a solid engineering career. Although both Mains and Advanced are the gateways to such premier Institutes, there are few marked differences between both of them.
Criteria 
JEE Mains 
JEE Advanced 

Difficulty level 
The questions are generally moderate in terms of difficulty but require a lot of practice. Solving a question in less than 120 seconds is the skill that students need to acquire. 
It requires months of dedicated preparations and is far more difficult than Mains. It evaluates the conceptual clarity, problemsolving and analytical skills of students. 
Eligibility 
Students who are appearing or have already passed their class 12th board exams can apply. 
The top 2,24,000 students from Mains are eligible to appear for this exam. 
Colleges 
NITs, IIITs, GFTIs and Private Colleges 
IITs and institutes like IISC and RGIPT 
Syllabus 
It includes concepts taught in Class 11th and 12th PCM. 
It has a broad syllabus. Applicationbased concepts are assigned more value. 
Exam pattern 
It is a single paper comprising of multiple choice objective type questions. 
It has 2 exams, namely, Paper 1 and 2 covering various type of questions like multiple correct types, match types, integer types, comprehension types, etc. 
The pattern is almost similar every year 
The pattern keeps on changing every year

Exam Pattern of IIT JEE 2019 Advanced
The examination is conducted in 2 parts, namely, Paper 1 and Paper 2. There are three sections in each paper. All the three sections have 16 questions from each Physics, Chemistry and Mathematics. The questions are objective type, comprehension type, match type, and numerical type in nature. Section 1 of paper 1 and paper 2 comprises of six multiple choice objective type questions. Every question has four options of which either one or multiple options are correct. Similarly, section 2 of paper 1 and paper 2 contains eight numerical value type questions. Section 3 of paper 1 comprises of two paragraphs with two questions each. In this section, out of given four options one option is correct. The section 3 of paper 2 contains two matching type questions. In this section, two matching lists are given with each having four options of which only one option corresponds to the correct matching.

Best Books for JEE Exam 2019
JEE preparation demands a lot of dedication and hard work. The students cannot afford to waste their valuable time on preparing concepts excluded in JEE syllabus. Also, picking the right set of books for both Mains and Advanced plays a crucial role in the successful completion of such a highly competitive entrance exam. Initially, the students must prepare all the concepts explained in the NCERT Textbooks. Over the past few years, the questions asked in the Chemistry section were picked directly from the concepts explained in the NCERT textbooks. Given below is the list of reference books that students can follow apart from NCERT Textbooks for better results in Mains and Advanced. However, the students should avoid using multiple books for preparing same topics as it might lead to the confusion of concepts.

Preparation Tips for IIT JEE 2019
Get your concepts right: Uncleared concepts might weaken your foundation and decrease your confidence. Therefore, the students are required to develop a proper understanding of concepts. The students must spend a majority of their time in practising a variety of problems.
Practice Question Papers: The students preparing for IIT JEE 2019 are advised to solve previous years question papers and sample papers. Practising question papers on a regular basis will help you to monitor your progress and gauge how well you are prepared for the examination day. Regular practice improves your speed and time management skills by familiarizing you with the examination pattern, difficulty level, the time required to answer different sections and more.
Proper Time for Revision: Proper time allocation for revision is crucial for the success of students in competitive exams. A regular revision of difficult concepts will enable the candidates to recall whatever they have studied during the examination.
