JEE Mains Question Paper 28 January 2026 Shift 1 will provide valuable insights into the exam type, subject-wise difficulty level and distribution, and the type of questions asked by NTA. The Shift 1 exam is over and the question paper will be provided here soon. The question paper was moderate with lengthy questions in Chemistry and Maths, but Physics was doable. After analysing the past question paper trends, we can predict that the later shifts of the exam session are generally more challenging than the earlier shifts and exam days.

For Day 5, JEE Mains Jan 28 shift 1 Physics paper was easy, while the Chemistry paper was moderate with lengthy questions and Maths was also lengthy. According to the students, they could not attempt Maths questions due to time constraints. Students have taken 1 hour each for Physics and Chemistry. Going through the JEE Main Jan 28 shift 1 question papers, students appearing in the April session will get an idea of the exam.

If you’re planning to study at Lovely Professional University, the cost depends on the course you choose. For example, B.Tech programs range from 1.4 to 1.6 lakhs per semester. Courses like BCA, BBA, or design programs fall between 70,000 and 1.2 lakhs per semester. Overall,tuition varies by program and duration. Apart from tuition, consider hostel, food, and other personal expenses. Hostel fees start around ₹80,000 per year and increase depending on the room type and facilities.

Yes, LPU is offering diploma programs in fields like Engineering (Polytechnic), Design, Management, Hotel Management, and other skill-based courses. Diploma programs usually last 2 to 3 years and focus on practical, skill-based learning. They are a good choice if you want to start working sooner or plan to join a degree program later through lateral entry. Eligibility depends on the course, but many diploma programs accept students after 10th or 12th grade. It is a flexible option, but you should check each program's details before applying.
