CBSE to Cambridge A-Levels :is the jump in essay writing and study depth as intimidating as it seems?

Hello there. I am currently a 9th grader in CBSE and want to pursue Creative Direction in the future. Because of this, I want to completely avoid heavy math, science, and social science in 11th and12th, and focus entirely on English Literature, Art, and Business.

Switching from CBSE to Cambridge A-Levels seems incredibly challenging to me. I wanted to know from those who made the jump, Is it really as intimidating as it looks? Does it require constant, high-intensity studying, or is it manageable if you are focusing only on subjects you love? Please share your experiences.
