That's a nice sentiment, but let's be real here. You can never make it into a respected economics doctoral program, and on the off chance that you do, you will never make it out. I'm not trying to be mean; it's just a fact that straight Bs and Cs after precalculus and trigonometry are a certain recipe for disaster, both in admissions and in coursework. If anyone says otherwise, they are completely delusional. Seriously, sugar-coating this with lies and false encouragement is cruel, disrespectful, and a great disservice.
