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.
