Yes — since you’ve passed all subjects in 2024 and retook PCM in 2025, you’re absolutely eligible for B.Sc. admission now. Your final marksheet will reflect the best scores obtained per subject, and universities recognize your updated scores once the improved ones are official. This meets typical eligibility criteria (i.e., passing all required subjects in 12th). Just be sure to carry both original and updated mark sheets during admission to avoid any confusion.
