Course Based Personal Statements are typical required for the UK, Hong Kong, Singapore, and many European countries. 

• In addition, some US colleges will ask why this major as a supplementary question and some of the more selective Canadian Engineering and Business programs will ask for your motivation. No matter what it is called, nor the length, the university wants to understand what drives to pursue THIS particular major. 

Consider your audience: Your personal statement is likely to be read by a professor of your chosen subject. Your job is to impress upon them your commitment and curiosity to your chosen field--keep in mind they have dedicated a lifetime to it. 

UCAS offers advice on effectively using AI in writing your Personal statement:

Applying for Multiple courses and Joint Degrees 

• You only write one personal statement to all your choices. Do not to mention a university by name, even if you are applying to only one university - your personal statement cannot be changed if you apply to a different place later. 

• If you're applying for a joint degree you will need to explain why you are interested in both aspects of this joint programme. 

• If you're applying for different subjects or courses, you need to identify the common themes and skills that are relevant to your choices. Please discuss this with your counselor.
