They have changed and constantly adding…
They have changed and constantly adding new programs. So keeping up with what assignments in which class has been extremely stressful. Not to mention the math teacher that my daughter has is very rude. During a conference she immediately came after me with all the things my daughter was doing wrong. Working in the education field I always start out with positives before talking about things that need to be worked on. Instead she got an attitude and then when I called her out on it she just went quiet and allowed the other teacher to take over. It is also advertised that there is a hybrid option which she did for 7th grade however that was not even an option for 8th grade. We chose this because she does competitive dance and requires us to be out of town for competitions. I was very upset with how this year went and we will not be returning next year. Also, for math her links work every day except for fridays. When she messages her teacher on Fridays saying that she is unable to get into the class with an access denied picture the teachers response is “well we are all here” she even sent her teacher a picture of the access denied message there is no response.
