Hello,
Based on your JEE Main Paper 2 percentile (96.3), CRL 2566, NATA percentile (88.69), and Class 12 score (88.8%), you have a good academic profile for B.Arch admissions.
Since COMEDK has its own merit preparation for B.Arch admissions, your exact rank cannot be predicted before the merit list is
Hello Student,
With your rank og 129537 as an OBC candidate, it is highly unlikely that you will get a seat in core branches. There is a possibility, though, that you might get a seat in lower-tier NITs or GFTIs, in branches such as Biotechnology , Mining, Metallurgy and Civil
Hello Dear Student,
Neither branch is universally "better"; it depends entirely on your interests.
Computer Science Engineering (CSE) focuses on software, coding, and algorithms, and generally yields higher immediate IT salaries. Electronics and Communication Engineering (ECE) focuses on hardware, microchips, and circuits, offering a dual-advantage of core hardware jobs +
Hey there,
With 94.95 percentile in JEE Main, Rajasthan home state, and REAP OBC-NCL merit rank 202, you have a very good chance of getting B.Tech CSE at MBM University, Jodhpur. While admission cannot be guaranteed until the official seat allotment is announced, your profile is competitive based on previous
Hello Dear Student,
You will not be able to secure a seat (CS or core branches) at the COEP Technological University with your current score. COEP is highly competitive, and closing ranks for the SC category normally range between \(\approx 10{,}000\) to (20,000), well below your (38,647) category rank.
