Mrs. Castelazo is a great teacher that knows a lot about what she is teaching. I took regular chemistry freshman year and it wasn't too hard. Especially with her as a teacher. I'm going to take AP with her this year. Although she is great at her job, she does pick favorites and that makes her class a bit more challenging. If you aren't on her good side then your whole year is screwed. You may still get a good grade in her class but it's a lot harder and pretty challenging emotionally.

She was wonderful, extremely nice and helpful. She was willing to spend time during lunch breaks to help individual students. Overall a great teacher.

You get used to all the course work. She is consistent in teaching, she has a routine. I honestly didn't know how great of a teacher she was until the year after I had her. I miss her! I learned so much from her! If she wasn't my teacher for chemistry, I don't think I would've understood any of it. We always reviewed a few days before the test. We took lucid notes as a class. Her lectures were straightforward and clear. You can have a good time AND still learn! She won teacher of the year!
