It honestly depends on the teacher, some are good a lot are bad. Teachers need to work together with the students to push and motivate them and to be there whenever there is a tear in the road. I agree in High School you should be able to help yourself, but everyone needs a mentor.
Students do not bother prioritizing homework or any school work. Students do not value education. School is represented as more of a "have to" thing. School is not interesting because of the way our Teachers and Administrators handle situations.
I am an current student at lhs. It is extremely stressful and the pressure is on. Kids easily fall into stress, anxiety, and depression. Some teachers barely know how to teach properly and effectively. However, the student body is extremely welcoming, friendly, and sometimes has the typical high school cliques. The health department and guidance department are both home to some of the best people in the school. The student needs to have to confidence and willingness to talk and reach out, not to fall down softly(or hard). It's a big school. Just need to get used to it. Though lhs is tough, there are wonderful teachers and some that aren't so great. You just have to get lucky.
We moved to historic and expensive Lexington, MA for the famous school system. The middle schools are great. However, the high school is a major disappointment. Half of the honors/AP teachers can not or would not teach. Our AP Bio and Honor's Algebra 2 teachers are so bad that everyone complains but the department heads defend them and berate the parents and kids. LHS is great ONLY because of the great parent and student body. If you have an average kid and not the money to hire a tutor, your child may sink and nobody would notice.
