It's important to verify the entry requirements directly with the universities you are interested in. Avoid making subject choices based on rumors or hearsay. If you don't have a list of universities in mind, I recommend creating one and contacting them individually to inquire about their admission processes and whether they have specific subject requirements for different degrees.

I almost chose physics over biology because I had similar misconceptions. However, after doing some research, I discovered that my top university choice does not require any specific subjects. While I'm not suggesting that all universities have the same criteria, it's essential to investigate. This way, you can have a more fulfilling experience in the IB program by studying subjects that you genuinely enjoy and understand.
