Hi i am new to IBDP

I will be starting with 11th grade IBDP in August, and this is the first time I have ever done IB, so I would love to know some advice, tips, and resources that will be useful. Also, I want to know what I should do pre-IB as I have around 4+ months, so pls help. I appreciate any help you can provide. This question would have prob been asked before, but I just joined this server today, so ye.
