What classes would be best to get accepted to an engineering school?

I’m having trouble with my schedule. I am currently doing the IB Diploma Program. My school doesn’t offer many subjects in IB. So there wasn’t much to choose from… My classes are: Psychology HL
Art HL
Spanish HL
English HL
International Math Studies SL
Chem SL

There’s also Biology, Film, History of the Americas. There’s Math SL, my school doesnt offer Math HL, and there also isn’t chemistry HL.

So I had these options, I really wanted to take IB, because I love how it makes you get involved, and gets you ready for college but I’m not sure if taking these classes would help me? I was also thinking of taking mix classes of IB and then taking an engineering class offered at my school, while also taking physics, and advanced algebra my junior year and then pre calc my senior year?
My IB coordinator wouldn’t let me take Math SL since I haven’t taken advanced algebra yet! :frowning: are the classes you take THAT important to getting accepted into an engineering school, I feel so behind and like I’m moving in the wrong directions. I have no idea which classes would be best. Can you please help me decide???!!
