Physics Analysis

• Paper was comparatively tougher than last year.
• Few Questions were formula based.
• Proper selection of questions proved beneficial to students as some calculations were Lengthy.
• Distribution of conceptually easy questions was uniform.
• Not many questions were asked from conceptually difficult areas.
• Some topics like Ray optics and Fluids could be ignored.
• Questions were designed to look tough with right approach. All questions were solvable or could be qualitatively analyzed.
• 12^th questions were relatively tougher than 11^th Std. topics.

Chemistry Analysis

• Chemistry paper slightly difficult than last year.
• Physical chemistry (Ionic Equilibrium, Stoichiometry, Electrochemistry) questions are slightly tricky & lengthy some questions involve more calculations.
• In Inorganic chemistry, questions from coordination compounds were tough. In general, Inorganic questions were of medium level.
• In organic chemistry, questions from Ethers & Alcohols were tricky. Most questions were from oxygen containing compounds.
• Overall chemistry paper is balanced but difficult to score or less scoring for Average candidate.

Mathematics Analysis

• Level in Synchronization with Mains but lengthier than last year.
• Questions from sequence and series (2 questions) and 3-D were lengthy.
• All questions were conventional. Students who have reasonable training and practice would have done better.
• Majority of questions were very specific to the topic only a couple of questions were of mixed topic.
• Level is similar as that of last year.
• Some questions were lengthy resulting more time consumption while solving.
• To score full marks may be difficult from point of view of lengthiness, but level wise it is scoring.

Overall Analysis

• Chemistry was tough, Mathematics was lengthy, and physics was having more number of difficult questions.
• Paper was not possible to easily attempt all questions in 3 hrs.
• This is the toughest JEE Main paper in last 5 yrs. Although there were 20-22 questions which were easy but about 22-24 questions were on a difficult side, so scoring 80-100 marks will be easily possible but 300 plus less achiever’s will be there in comparison to last 2 yrs.
• Expected cut off marks would be around 75 marks for general category.
