I noticed the newly added "Practice" tab added to AP Calculus AB and BC and I just wanted to say a big thank you to the team at KA!! This practice tab, with the compilation of all the practice questions in one place, is truly a life-saver! KA has made my teaching career so much more rewarding and made my life so much easier/better.

So from the bottom of my heart, thank you all for all that you do!! My students and I truly love this site.

Sincerely,

Navin Sawalani
