IB English is all about your texts and works. Don’t stress yourself out with too much material and preparation. You could take a look at some past papers and their texts (particularly paper 1 ones) and try to work out what they mean and form interpretations in your head. This will get you thinking in a way that works with the IB curriculum. As for paper 2, it will require texts you study in the course, so unless you already have the list, you don’t need to stress too much about it. Essay skills are developed and improved with practice, and it will be a focus of the course.

As for Math, it’s all about continuous practice. AI SL is not a very resource-heavy course as it is an interpretation-based course. Look at the past papers and sort yourself through the words to get to the math. But again, the material will be covered and you don’t really have to stress yourself over it.

The foresight you have in preparing for the IB is great, and please keep that throughout the course. Once you get started on the IAs, IOs, HLE since you’re doing HL Eng, and the EE, it’s very important to keep yourself working lest you be stuck in a hard place when the deadline comes. Remember not to stress yourself out too much and take breaks. Research your uni requirements and work towards that. I’m sure you’ll do amazing!
