I completely understand that Chana, I've been in your situation numerous times with my to sons and felt the same way. Indeed it can be frustrating. Try to use any situation possible to pull something positive and educational from it is my thought pattern.
Especially as a GT parent, I've learned to pick and choose my battles. If I went into school / wrote e-mails of concern every time I thought there was an injustice involving my child's education, I'd be doing so almost daily and it would simply wear me out.
