advice for AP lang/comp, world, micro, ush and psych PLEASEE

hey people so i'm at an all IB school (sophomore) and i'm taking all MYP classes (i'm in AA SL tho rn) but our school lets us take some AP exams offered thru the school for free (emphasis on FREE)

those are:

-AP English Language and Composition

-AP World History

-AP Psychology

-AP US History

-AP Microeconomics

because they only offer the exams (not classes) i'm self-studying WHAP, lang/comp, and micro this year and am planning APUSH and psych for next year (my junior year)

my thought process is (and please tell me if this sounds insane) is that i'm taking economics (technically not an IB class but its a graduation requirement) so that kinda goes with micro, WHAP bc i'm taking myp humanities world history, and lang/comp kinda just because i wanna do three this year and two next year

my biggest question for y'all though is how hard do you think each of the exams are withOUT taking the class? cuz when i was searching it up and stuff most of the resources were for people who are also taking the class so i wanted to post on here to see if any of you guys have done something similar or might have some insights

okay thanks in advance :)))))
