Ds1 is in year 10.
Yesterday i received a letter from school informing me of the dates he sits science gcse's. Next week!!!!
This is the first i have heard of it!! I assumed he wasnt sitting any til next year as he is doing triple science.
Turns out ds1 has been aware for some time but hes so laid back that he didnt think to tell me! 
Im fuming at him
and not impressed that there was no prior warning from the school.
