Pre-med to IB

<p>Hi,</p>

<p>I am in 2nd year of premed but I will change to an economics or computer science major these year. I will finish it with 23 years, so I will be too old to get in IB?</p>

<p>It's easier to get in IB with economics or computer science?
What are my chances of getting in IB?</p>
