I have heard a lot of toppers mention that going through Mrunal videos is enough for economics along with current affairs. I am from south India and cannot understand hindi which is what he uses in his lectures. Are there notes available for what he teaches in his channel? I can't understand what he says but is seeing the slides he displays enough to get a jist of the topic? I don't find economics tough but it doesn't feel easy either and most standard books are too hard to read. Is there any other source to understand basics from?
