<p>One does not have to come from high income family to take AP classes. AP Calc will replace 2 math courses in college and that’s’ what she’s ahead. Mine has never taken 16 units, a little less but not 12. She took a gamble and did not take the introductory courses for her major, because of that she was able to skip 2 classes and took the harder one for students with more experience in computer science. She ended up with a sophomore class in her last quarter. Next quarter, she may take 16 units but I still see a lot of slack in her schedule going forward. </p>
