Any advice on how to prepare for the descriptive part(PEB) for someone who doesn't have any formal training in economics, i.e., I've gone through the prescribed texts, but I've got absolutely no idea about where to practice the numericals(ISI level) from.
Can you guys recommend any books, links to solved problems etc. ?
