I am slowly going mad

I am giving university students feedback on their writing. The report I am currently reading begins with the sentence: "A reality problem in mathematics is an attempt to attempt modelling population over time." It does NOT get better further along.

AAAAAAAAAAAAAAAAAAAAAAAAH. *beats head against wall*

(Well, actually the sentence was: "Ett verklighet problem inom matematiken är ett försök till att försöka modellera population över tid." But I did my best to capture the multiple levels of bad writing in English.)
