I failed my class 12 CBSE regular year, and again the next year as a private candidate. Can I appear for it again on the upcoming year?

Yes, as an Indian student, if you have scored above 80% then you can submit these scores. Given that these scores are awarded by any of these bodies - CBSE, AISSCE, CUSCE or ISC. 

The students won't even have to take IELTS or TOEFL for UCD if the given English language requirements are met. 

Yes, NUCAT syllabus is similar to high school Class 12 curriculum of CBSE, ISC, and various state boards. Topics covered in Mathematics, Physics, and Chemistry are generally based on topics taught in Indian schools. Students who have studied under CBSE, ISC, or state boards will find familiar topics in NUCAT exam. There will be difference in type of questions asked in NUCAT 2026. It's always recommended to check official syllabus provided by the institution, as some topics have a slightly different focus or emphasis based on course or programme requirements.

There's no single minimum salary, but CBSE teachers generally start from ₹10,000-₹25,000/month, with fresher ranging from ₹1.2L-₹4.5L/year. It varies depending on the location and school type. 

Class 11 syllabus is vast. It is lots of theoretical concepts. Also, there are many formulas to remember. One who have good grip over concept and formulas can easily qualify the examination. Some of the important chapters in class 11 Physics are Laws of motions, gravitation, oscillations, thermodynamics, etc.  These topics are also important to prepare for competitive examination.
