Should i go to a driving school to learn to drive stick (manual)?

If you can find someone who can teach you (such as a friend or close family members), it would probably be better to do it that way and save the money. You can learn it in a day, but of course just as in everything else, you'll have to practice until you get it down. I would say it takes at least a week of driving around practicing to get used to it, after about a month of driving it regularly it will just become second nature.
