Good question. The answer is always as soon as you sign up. Because there are so many students taking the bar exam these days, it is important to act early to make the experience as pain free as possible. The bar examiners usually suggest a few hotels on their website which offer discounted rates. If you’re taking the exam in Ontario, the ayers hotels are always nice and have reasonable rates. If you’re taking the exam at the century plaza, your best option is to stay in that hotel. While it is a little expensive, it is worth the extra cost. There is nothing better than not having to drive before or after the bar exam. So, if you haven’t made your reservation yet, go ahead and do it now while there is still time!
