Depends, some are some aren't.
However, in my opinion, the thing that makes student loans crazy is how the payments are structured.
With other big lifetime loans (mortgage, car, etc.), they are structured with a fixed term and the interest is factored in from the beginning. You pay $X a month for Y years, and that's it, it's all paid off. All you have to do is keep up with those payments, and you know how much they'll be from the time you agree to the loan.
Student loans are structured more like credit cards. If you just pay how much they tell you to, interest will accrue, the loan grows, it capitalizes, and the term is indefinite. You can pay on it consistently for decades and never make any progress.
There's practically no assistance to figure out how much you really need to pay, and sometimes even attempting to overpay to cover the interest doesn't help, as they'll apply the extra towards the next payment instead, and so extra interest still accrues.
