It's difficult to give you an exact KCET rank with just your PCB marks and KCET score. The Karnataka Examinations Authority (KEA) considers both your 12th standard PCB marks (out of 300) and your KCET PCB score (out of 180) to determine your rank, giving equal weightage (50%) to each.

First, let's calculate your percentage in PCB in your 12th standard. A score of 384 out of 300 is unusual as the maximum marks are typically 300. Assuming there might be a slight misunderstanding and your PCB total was out of a different number, or if 384 is your total marks across all subjects and we need the PCB component, the calculation would change. For the sake of providing an example, let's assume your PCB marks are 280 out of 300, which gives you approximately 93.33%.

Next, your KCET score is 110 out of 180. To combine these, we need to bring them to a common scale. Your normalized KCET score out of 100 would be (110/180) * 100, which is approximately 61.11.

Now, your composite score for ranking would be (50% of Board PCB percentage) + (50% of Normalized KCET PCB score) = (0.50 * 93.33) + (0.50 * 61.11) = 46.665 + 30.555 = 77.22.

Based on previous years' trends, a composite score of around 77 might place your rank somewhere in the range of a few thousand to possibly within 15,000 - 25,000 . However, this is a broad estimate, and the actual rank can vary.

Regarding career choices with a PCB background, you have a wide array of options:

• Medical Field: MBBS, BDS, BAMS, BHMS, Nursing, Pharmacy, Physiotherapy, Occupational Therapy, Medical Lab Technology, Radiology, etc.
• Allied Healthcare: Optometry, Audiology and Speech Therapy, Nutrition and Dietetics.
• Biological Sciences: Biotechnology, Microbiology, Biochemistry, Genetics, Botany, Zoology, Forensic Science, Environmental Science.
• Agriculture and Veterinary Sciences: B.Sc. Agriculture, Horticulture, Forestry, Veterinary Science and Animal Husbandry (B.V.Sc & AH).
