In theory, it works, but on a small scale. say you skipped Derivatives. 5-15% is a big range, but if you really can nail down the others, that’ll still get you a pass. worst case, say derivatives ended up being 15%, statistically, you should grab 5% with random guessing. you max out at 90%. That’s still a lot higher than the 70% safe range.
As soon as you start gambling skipping 2 or 3 sections, then your chances of failure increase dramatically. |
