hi. I'm currently in year 11 and I'm moving to a new school next September for year 12 and 13. id like to take economics, history, maths and further maths. I also would like to do things such as young enterprise, gold DofE, EPQ and hopefully work experience over the summer of yr 12. however, I am told that this will all become too much alongside my regular extracurricular activities. how should I manage to do all of this and still achieve high grades? thanks.
