Cooking spaghetti and other pastas: do you always get it right?

I hate under-cooked pasta. Have you ever eaten it where there was a big hunk of uncooked pasta in the plateful you had. My mother taught me to put a little bit of oil in the water where you boil the pasta and stir it a few times while cooking. Keeps it from sticking together!

Well, there is 2 ways. One is to bite into it to make sure if it is just right. My dad taught me this secret. Just take a piece of pasta and throw it onto the fridge. If it does not stick, cook it more. If it sticks, it means that most of the pasta is cooked. I would reccomend using both methods.
