I thought I would love Biology this year but that became the total opposite. I learned nothing this year I tried my hardest to understand what she was teaching but I failed the entire year. I honestly wish she was replaced because she doesn't show tough love to her students like other teachers she is too nice! She doesn't give homework which frustrates me because she says she doesn't want to overwork us which I can totally understand but the whole point in a teacher is to challenge students.

She's a nice person but an awful teacher. You is very unorganized and you won't do a single thing in her class. We once did a huge project and she never graded it. Also she is bio teacher I see in the other reviews they are getting mixed up with the chem teacher Mrs.Pereira who is actually who cousin in law.

Great teacher. My son struggled with chemistry and she never gave up trying to help him. Most teachers write him off because he is not great at finishing homework or assignments. She pushed him and prodded him and got him to do lots of work for her. I hightly recommend this teacher to anyone.

Mrs. DaCosta is very laid back and lets her students do pretty much anything during the period. While that sounds awesome, it doesn't make for a very good teacher. The entire class in on their phones even when she is talking directly to us, and she always gives us points for assignments without checking for completion. All you have to do is show up. She's very sweet, but I feel thoroughly unprepared for AP Biology next year. Yes, it's an easy A if you can learn from the textbook for the tests.

If you happen to be in her class, expect to have practically no lectures and direct helps from her, unless you actively ask for help. But that won't work out too well since she's quite frequently absent anyways.

She is extremely unorganized and does all her prep in class. Once she left cups of milk from an experiment out over the weekend. She'll do anything to help you individually, but from a class standpoint she is awful. I learn more from the 10 second clips than from her. She interrupts her lectures with random annoying tidbits like "aren't scientists dumb." She's so nice but such a bad teacher.

Mrs. DaCosta's a really great teacher. She obviously loves Biology and kids, and she's really easygoing and helpful. Her class is also pretty easy, you can maintain an A with relatively little effort. Since she's so easygoing, sometimes kids take advantage and goof off, but you still learn a lot.

She's probably the best regular Biology teacher on the campus. One qualm I have with her is with all the freaking art work we had to do as we learned biology. This isn't an art class DaCosta! If you hate art/drawing/coloring, this class is still the best one to take as the other bio teachers are harder.
