Hope someone can advise me what to do in this situation. My DS is in Year 13, one of his A-levels is Further Maths (FM). At the beginning of this school year, students doing FM chose what to do: 2 majors or 4 minors. My DS chose 4 minors and on the first week of doing his 4 minors he found out he has no maths teacher who will teach them ( it's 4 of them). Since then, Maths Subject Leader said that they need to teach themselves on Google Classroom, where she put some study materials while she try to sort it out very soon. Later on "very soon" transformed to "by the end of the half-term". When end of half-term happened, she said "at the beginning next half term it will be sort it out". Yesterday was first day of new half-term and of course the issue is still there. Now she says "it will be sorted out soon". At the same time, his Head of Year approached him and stronly advised to drom FM A-level and do AS-level instead, my DS refused. After that Head of Sixths Form approached him and again "strongly advised" to drop FM A-level. As his predicted grade for FM is B, I suspect this is their attempt to solve the issue by less painful way for them, but not taking into ccount his best interest. As all this happens through talking with his Maths subject leader, it looks like they will push him and few others to study FM themselves as long as they could and they are really missing out on proper studying and they do the same level on tests as other, who do have a techer. I need an advise how to approach school regarding this issue and finally make them to teach these 4 students properly. Should I contact Head teacher, or go straight to Governors? Just for reference - I am not familiar with A-level system at all, he is our first who is doing A-levels, and probably it's a norm when students learn themselves?
