The classes Mr. Gualcherani teaches are generally a bit more challenging than a lot of other courses at Keppel, but Mr. Gualcherani is helpful and wants to set you up for success. His curve is very generous, especially at the end of the first semester, which makes up for the test difficulty. If you are attentive in his AP classes, you are almost guaranteed to pass the AP exam, and you will likely earn at least a 4. Just listen to his lectures, take notes as appropriate, and ask for help when you feel that you aren't understanding anything, and you will do well!
