New student - can anyone tell me about the placement tests?

So I’m going to be joining Purdue this August and I’m told I am to take two placement tests: ALEKS and the CS Placement test. I am aware these tests are to measure my knowledge of the field and it is to place me in a particular class.
I was wondering if anyone knows the curriculum of these tests?
I am very good at maths, so I am fairly confident about ALEKS. Could any current students tell me what’s the minimum scored required to get into the most advanced mathematics class? I did take a practice test but I couldn’t make head nor tail of what my score meant.
As for the CS placement… well, the only computer language I know is C++, and I am fairly a novice. Which languages are going to be tested? Is it ok if you’re placed in the most beginning class?

Literally any input on these placement tests will be welcome. Thanks!

I think you need a 70 or 75 to get into a calc 1 class. I remember there being a chart online somewhere. It’s a lot of algebra and trig.
