<p>I have been sudying this book during the last 2 weeks or so. Went through all the material and took more than half of the model tests from the back. I could describe my testing experience as fair, could solve 35-40 questions easily on each test BUT was stuck on the remaining 15-10. So I decided to take a Sparknotes test(I had heard they were quite similar to the real thing). </p>
<p>Took the first one carelessly, scored 730 and took the 2nd the next morning, scored 750. Found myself disappointed. Reviewed my test mistakes and found a couple of typos and a wrong answer explanation, which made me think twice before seriously considering Sparknotes. </p>
<p>Now I'm in a dilemma. Shall I study Sparks' and try to figure out their mistakes or shall I get back to Barron's? Besides, if i get back to Barron's what's the best way to maximize my score?</p>
<p>Do both, that's what I did and got an 800. Take all the Barron's tests and review as you need to. The questions are way harder, but through practice with that, you get a lot better! Sparknotes, despite the errors, is pretty close to the real thing, as far as I could tell. Take all the tests you can and you'll get better and better.</p>
<p>I did both and sparknotes really has too many mistakes. Barons is awesome and I didn't find that their tests' difficulty really surpassed the real one by much. The most important thing, I think, is to know how to work your graphics calculator. If you're smart about it and understand the concepts, then it's not hard just to plug and play. </p>
<p>Why can't you have a graphing calc, since Collegeboard does say that it is required for some questions? You can't borrow one from school or a friend? There is undoubtably some way to get your hands on one, and taking it without one would be stupid.</p>
<p>Actually I may borrow one from a close friend, but I'm not sure wether I can adapt myself to make proper use of it on the test day. It's less than 3 weeks away and I haven't crammed for biology yet.</p>
<p>I am also considering to order one from the US but delivery to Europe will take a lot of time I suppose(as it did for my books).</p>
<p>You need to get one. Just spend some time with it (Barron's has a short section on it) and get use to its abilities. It can be very helpful with a short amount of "practice". If you can get one, DO IT</p>
