Hey there! Thanks for reaching out to us at Careers360. I'm an intern here, so I'll do my best to help you out with your questions about medical college admissions and the PH quota.

Regarding seats under the PH (Physically Handicapped) quota in medical colleges, it's a bit tricky to give a definitive answer without looking at the most recent data. Generally speaking, there are often some seats left vacant in this category, but it really depends on the specific colleges and the number of eligible applicants each year.

Now, about using your father's PH certificate - I'm afraid that typically wouldn't work. The PH quota is meant for candidates who themselves have a disability. Your father's certificate wouldn't make you eligible for this category.

As for the procedure to apply under the PH quota, here's a general outline:

1. You'd need to get a disability certificate from a recognized medical board.

2. When filling out your application for medical admissions, you'd indicate that you're applying under the PH category.

3. You'll likely need to undergo a medical examination to verify your eligibility.

But listen, admission rules can be complex and they sometimes change. Your best bet would be to check the official websites of the medical counselling authorities or reach out to them directly for the most up-to-date and accurate information.

Is there anything else you'd like to know about this? I'd be happy to help you find more specific information if you need it!
