Hello,
You cannot get admission to engineering courses in Delhi University (DU) through CUET scores .
DU offers engineering courses under its Faculty of Technology, and admissions to these courses are based on JEE Main scores, not CUET.
Hope it helps !
Hello,
Delhi University (DU) offers various engineering courses under its Department of Technology.
Admission to these courses is primarily based on the Joint Entrance Examination (JEE) Main scores. However, some courses may also consider CUET (Common University Entrance Test) scores for admission.
The exact number of seats filled through CUET scores can vary each year and are not publicly disclosed.
Hope it helps !
Admissions for CUET aren't solely based on 2 Non-Med Percentage along with JEE Mains percentile. The eligibility criteria for CUET require students to have scored at least 50% marks in their Class 12th exam for general candidates and 45% for reserved categories.
Additionally, CUET has its own exam pattern, which includes multiple-choice questions divided into three sections:
- Section 1: Language proficiency(English/Hindi/regional languages)
- Section 2: Domain-specific subjects
- Section 3: General Aptitude
It's also important to note that while JEE Mains is a separate entrance exam, some universities may consider both CUET and JEE Mains scores for admission to certain programs. However, the specific admission criteria may vary depending on the university and course.
To confirm the admission criteria for your desired course, I recommend checking the official websites of the participating universities or contacting them directly.
Yes, if the CUET UG application form does not ask for the 10th marksheet upload and only requires a photograph and signature, your application should still be considered valid. Since you are currently appearing for the 12th exams, the system may not require additional documents at this stage. However, double-check the official guidelines or contact CUET support to confirm.
A PG (Postgraduate) degree in Forensic Science, specifically an M.Sc. in Forensic Science, is a two-year program that provides specialized knowledge and skills in the scientific analysis and application of techniques for collecting and analyzing evidence to solve crimes.
