I would firstly congratulate all the candidates who have qualified to appear for the JEE Advanced examination. With the JEE Advanced just a few days away, the pressure must be mounting on the students. As a teacher and as a student I once was, I can understand the mental trauma that most of the students are going through during this time. Over the years, I have seen that people who are mentally strong, positive in their approach and most importantly have self-belief, emerge successful beating the odds against them. Here is a brief subjectwise analysis of how to go about your JEE Advanced in these final important days.
Chemistry: Just like in Mains, chemistry will be the rank deciding factor in JEE Advanced, too. Looking at the last 10-15 years’ papers, one can easily assume that all physical, organic and inorganic chemistry have relatively the same weightage. Do not waste too much time on lengthy questions or questions without solutions while practising for physical chemistry. Revise all the standard titrations that you come across during your laboratory experiments. I will lay stress on general organic chemistry and isomerism as in any paper they can fetch you easy marks. Revise the important name reactions, their mechanisms and practise two-three questions on the same, as JEE has a tendency of giving a few questions based on popular name reactions every year. Revise the important tests and reagents used to distinguish and detect different organic compounds. Pay heed to topics like biomolecules, polymers and chemistry in everyday life. Pay special attention to inorganic chemistry, as it is the most efficient way to score in chemistry. In salt analysis, read your lab manual well and go through the preliminary tests (flame test, bead tests etc).
Physics: The JEE Advanced paper for physics will be a notch ahead of the difficulty level of JEE Main. Do not expect a question on direct formulae. Due to the very nature of mechanics, a word of caution for students who think this part is their forte, do not get stuck! This is the part where a lot of speed breakers can be inserted in the physics paper, so be careful when you attempt the questions. Also a very high potential area for negative marking, so attempt less but attempt accurately. Most of the questions in electrostatics and mechanics can be done easily if you have derived the basic formulae. While geometrical optics is a cakewalk if you just revise the standard profile of questions and sign conventions, you can expect slightly difficult question in wave optics.
Modern physics is by far the most scoring topic in the JEE Advanced physics paper. Make sure that you do not make silly mistakes in calculation and conversion of units. Properties of matter, surface tension, semiconductors, experimental physics (Wheatstone bridge, diffraction etc) are topics that students ignore conveniently.
Though these are small topics, the number of questions asked from these can combine together to replace a big section. Kindly go through all your lab experiments and see the assumptions and calculation involved.
Maths: Do not start with any new question bank or a topic which you have not covered till now. Coordinate geometry and calculus will help you sail through the cut-off and score heavily. Remember important properties of conic sections and different forms of equations (tangents/normals) as it will greatly increase your speed. Do not spend too much time on topics of algebra like complex number, matrices, solutions of triangles and binomial theorem. Scoring topics such as probability, vectors and 3D should not be skipped. Be thorough with basic inequalities you come across in complex number, sequence and progressions and trigonometry.
Overall: There are no fixed ways of how to attempt a paper and maximise your score, because it varies with every individual. But while you take your mock tests, you will understand that a given pattern of attempting questions, selecting which subject to solve first will yield you the maximum output in terms of accuracy and number of questions attempted. You should practise more to build on this strategy of yours as selection of questions in a right manner will be an important aspect of a tough examination like JEE (Advanced.)
When you start writing the paper, ensure that you maintain a steady pace during the three hours of examination. Students usually have a tendency of starting slow and rushing towards the end, which greatly reduces the accuracy level.
At times, you will encounter questions that are speed breakers or the ones, which you are not able to solve after spending a considerable amount of time. If you find that a particular section (physics, chemistry or mathematics) of the paper is difficult, do not panic. In such a case, remember a difficult paper is difficult for everyone and start looking for questions which are easy. This will not affect your rank, as most of the candidates will not be able to solve the difficult questions in any case. Students who have a tendency of studying late must change their sleep cycle and study every day from 9am-12pm and 2pm-5pm (JEE examination time) to make it the most productive time period for them to score.
JEE Advanced (Architecture)
The syllabus for physics, chemistry and maths in this section will be the same as that for engineering aspirants. Though it sounds trivial but bring your own set of geometry box, erasers, pencils and crayons.
In sections like freehand drawing, three dimensional perception, maintain your composure as these require high concentration while attempting.
Architectural awareness can be highly scoring, so browse through the famous architectural designs (both places and persons).
Expect some good questions in imagination and aesthetic sensitivity.
Geometrical drawing can be a cakewalk if you have sound mathematics fundamentals about geometrical structures.
Summarily, it is more of an aptitude test that assesses your ability to visualise things. As it is true for any aptitude test, there is no definite method to approach the paper as it will vary from individual to individual. Keep track of time as some sections of freehand drawing may be time consuming for a few students
