JEE Main Jan 23 Shift 1 Question Paper 2026: Which was the toughest and easiest sections?
The Mathematics and Chemistry portions in JEE Main 2026 question paper shift 1 were the toughest, while the Physics section was doable. The Math section consisted of lengthy questions and a few topics from the deleted syllabus. The Chemistry section had a good number of tricky questions, especially in the Inorganic Chemistry section. The Physics section majorly comrpised of application-based questions. Our subject-matter expert, Miss Puja, was quoted as saying,"Emphasis was given more on application-based, time-consuming questions. Chemistry was tough, which might result in a decline in percentile."In the previous year, the Day 3 JEE Mains followed a similar format, although the overall difficulty level of the exam slightly varied.
Preparation Takeaways for JEE 2026 Upcoming Shifts
Here are a few key suggestions for students who are appearing in the JEE Mains 2026 for last-minute strategies:
It is best to focus on topics which are high-yielding with lower efforts for the last-minute preparation. These topics include Semiconductors, Biomolecules, Statistics, Algebra, and the like.
A good way to remember different formulae and important areas is by practising the 3Rs, or Review, Recall and Repeat.
It is important to put equal focus on preparing the topics with maximum chances of repetition from previous years’ questionnaire.
To improve time-management skills, it is the best to practice mock test papers at home for the last-minute touch-up.
To sum it up, the JEE Mains Question Paper 23 January 2026 Shift 1 will be available here along with the answers after 12 PM. The unofficial question paper is released first based on the students’ reactions and experts’s analysis. NTA will releaseJEE Main 2026 answer keyalong with official question papers andJEE Main response sheet 2026after the end of session 1 exams. We wish you all the best!
