My strategy for writing essay was critical.I discussed common points with different perspective.E.G: i discussed constitutional supremacy in terms of personal identities of leaders,moreover,i discussed political instability in terms of immature behavior of leaders who invited military.Also,i discussed unemployment with comparison of rate during Great depression(1920) which was 10% and we are having 6%.I put simple facts known by everybody so i guess its wrong to say that they need facts but i guess what they need is your point of view which is also literal meaning of essay.I focused on two things:

1.Organization of outline and coherent essay
2.Common points but with "different" dimension.

I took 8 lectures and wrote 3complete essays.I hope I helped.
