You must look and judge the suitable atmoshphere surrounding that particular area of interest , the scope after the degree, and in the process of graduating. You must be aware of the facts and figures relating with the companies offering jobs , or even doing a P.G for that matter. You must have your vision clear and sorted in depths regarding your field, as it would help a lot in the upcoming years of graduation , and you will build on that even more in the 4-5 year process.
