Apart from English and Maths, most jobs don't need your child to have studied a particular subject at GCSE level. Most employers will probably be more interested in your child's range of study, their grades and if they enjoy learning. Some jobs need A-levels or degrees and some jobs need particular A-levels, so if your child has their heart set on a particular career, please check what they need.
Also make sure that your child is not basing their subject choices on things like:
• wanting to stay in the same class as their mates
• wanting to keep the same teacher
• thinking that some subjects are not as much work.
Because of different timetables, they may not stay in the same class, teachers may change and they have to be prepared to work hard in all subjects.
