    Hey,

    So we aren't allowed to talk about the ISA or EMPA assessments themselves, but we are allowed to talk about the different practicals and investigations our teachers have been getting us to do in preparation.

    I'm particularly interested in this as this year I decided to self study, so I haven't been in a classroom and done any chemistry practicals at all :s

    Please share your experiences, and tips your teachers have given you, and point me to any good online resources you may have used.

    Thanks

    This seems to be generating PMs for me, but not much else...

    Surely you've all been doing practicals in class this year (and last)? What were they?
