Um, yeah. Before high school, I don't think I ever studied once. Ever.
And even now that I'm finishing high school, I have the worst study habits. There are only a few select subjects that I will pick up my text book and make study notes for before a test. Same with reading; I'll only read over my test material the morning of the test--or more likely, in the five minutes before class starts.
I'm trying to improve though. I spent a fair amount of time today studying for the French test I have tomorrow...! Better than nothing. XD
