You should have worked closely with a prof during your time as an undergrad.
I thought that i would like to go on to grad school so i have purposely set myself up to have as big of an advantage as i can.
Over the last year i have worked closely with a prof on a research project, used data from the project to present a paper at a professional conference, and I am finalizing the paper to submit for publication. I also entered the paper in a student paper competition sponsored by the professional association and won the undergrad division.
I cant underestimate how much i have learned doing this. I have the greatest respect for the amount of work that it will take to earn a graduate degree and have made great contacts at grad schools by doing this.
If you are seriously considering grad school, start talking to your current profs asap.
The way i look at it, grad school will about as different from undergrad, as undergrad was from high school.
It is a major step up in expectations and if you arent willing to put in the effort, then it probably wont work out for you.
Biggest understatement of the year.
I am in the process of getting my PhD in economics and I do not think I will finish. I will prolly end up getting my master's in economics with the concentration in finance, then get my MBA, and maybe return to finish my PhD some day in the future.
Writing the dissertation is not a much a big of deal as learning statistical programs.
If you school offers a "Data Gathering and Analysis" type of class, I would highly suggest you take it.
One of my classes requires us to do this as just an assignment
create topic, gather data, analyze data, input data in equations, test the results, review with other classmates (to check the work, conclusions, etc).
The data gathering is far more elaborate than typical "searching the web. We have to purchase rights to economic databases and then convert the data in something that can be read by statistical programs. Since you are in the liberal arts, you will probably be using SPSS for your research.
Go for it. Even if you fail, you can get a master's. And you wouldn't believe the respect you get when you tell people you are in the PhD program.
