She is very knowledgeable and helpfu. She stays afterschool and students can go to her for help. Gives a lot of homework, hard tests, she expects students to work hard and put in a lot of effort. Even though she may be a hard grader, she is very nice and is willing to help her students succeed if they come to her.

I can't say she's the best teacher, but ad long as you do what she says, Ms. Leon won't be on your trail. I feel very bad for her though because many of her PE freshmen act up and cause her so much trouble. Then, she gives lectures; that's why kids don't like her. Shes very lonely too. She knows what she is teaching. If you pay attention, you'll get an A. If you're not really physically fit, put in effort, and you'll get an A.

She should honestly stick with math. She gives the whole class a bad grade because of a couple bad students. Thanks to her, I have a horrible citizenship grade. She is also unclear when she teaches and believes she is always right even when theres proof she isnt

Honestly, Ms. Leon isn't that bad. She gives a lot of homework because unlike other teachers, she actually wants you to understand what you're doing instead of memorizing everything. She knows her material really well and can help you if take the time to ask her for it, but she expects you to at least try. You'll definitely do bad if you slack off though, so be forewarned. All in all, Ms. Leon cares a lot :) On the bright side, she's funny in a weird way and does Harvest of the Month!!

Yes, Ms. Leon is hard, but that doesn't mean you can't get an A in her class. If you take her class, you HAVE to do your homework every single night. It takes about 2 hours, so if you miss a day it'

Almost everyone has something negative to say about her, but she isn't that bad! If you try hard, then you will pass. Ask her for help, and she will help you! She honestly wants you to do your best.

Can be confusing. She goes fast because she expects a lot from you. Not too hard if you pay attention. She doesn't teach it first because she wants you to think about it.
