I'm currently studying in year 11, and in about January this year my maths teacher moved me down to foundation level i have tried so many times to ask him and even the head of maths to move me back up which he said would happen in 3 weeks but still hasn't!!! I'm getting really frustrated and feel like giving up all together! I don't know what to do know he gave me a test before last half term to "show my performance" but hasn't given my paper or even told or hinted to me that I will move up again. He said to me in year 10 that I'll definitely be doing higher and had lots of faith in me but after year 10 was done, he became very weird towards me i supposed he didnt like then...
Please help me what should i do to finally persuade my teacher??
