DESCARGO DE RESPONSABILIDAD: Estos folletos proporcionan un esquema “general” del material con problemas de práctica y respuestas. 
Cada instructor puede presentar el material de manera diferente, por lo que no todo el material en los folletos puede ser cubierto por cada instructor, y algunos instructores pueden cubrir material que no está en los folletos. Por favor revise las grabaciones, notas, diapositivas y texto en línea de su clase, y compárelos con los folletos para anotar los temas apropiados. El material para los cursos introductorios (103, 104, y 109) se carga gradualmente durante el semestre; el material para los cursos orgánicos (343 y 345) está disponible de una vez.
Si encuentra un error o tiene un comentario sobre los folletos, no dude en comunicarse con Tony Jacob en atjacob@wisc.edu. Dirija sus preguntas de química a Piazza o a su asistente de enseñanza (TA).
Si desea proporcionar comentarios, hay enlaces disponibles para los recursos orgánicos todo el tiempo; para los cursos de introducción a la química, se proporcionará un enlace cerca al final del semestre. Siempre apreciamos los comentarios, así que gracias de antemano.
Aquí hay otra herramienta útil: un calendario semestral de otoño. De esa manera, puede agregar todas sus tareas para cada clase en los cuadros usando un bolígrafo de color diferente para cada curso.
This is an accordion element with a series of buttons that open and close related content panels.
