Went from 168/169 plateau to consistent mid 170s. Took a practice test every day and reviewed the misses. Use analytics to diagnose which question types you struggle with and practice them. Also, when you are taking the test really try to employ what you believe are the best practices, don't worry to much about the score. Treat it as the highest form of practice and continually refine your approach. Hope it works out!

This is a good question. In the stimulus, when it says "The Anthropology Chair had told James that his proposal had her endorsement, but only if the draft proposal she saw had all the recommendations..." I think we are to preclude any other variable or conditions. In other words, the only way that James does not get the endorsement ("his proposal had her endorsement") is only if the proposal fails to include all the recommendations he made. In that case, E is not only sufficient, but also necessary as it is the only way the endorsement condition could fail.

Hope this helps in some way.
