but to answer the OP, your two cousins who have not found employment yet could be based on numerous reasons. eg, what uni they went to (yes it's an important factor in law), degree class, or they could've not done any extra-curric' activities at uni or not have had any work exp (vac schemes) too. also, you're only in year 9! the whole economic and legal climate by the time you apply to uni and GRADUATE may be different or better.
