“Over prepare” essentially means to prepare adequately and then prepare some more!!! I had a high school track coach that said, “You can never over-prepare! (usually right before he would add: “OK, now let’s do it again!”) In job interviews, you want to over prepare so you know your subject (about yourself of course, as well as about the company you are seeking a job with) and that way you’ll be ready for anything that may be asked & sound natural in your response. In studying English, look through all the materials they have given you or requested you to buy, plus check the references cited because they may contain that extra bit of information that will give you the missing piece of the puzzle to “fully” prepare you and aid in your comprehension.

“Then go with the flow” is a phrase used in modern English to help convey meaning to you & like water, help you envision going down a river in a canoe. Don’t try to paddle upstream — it’s much too hard and you won’t get very far with even your best effort. If you go with the flow, you can expend minimal effort and still enjoy the sights along the journey downstream. For your benefit, and to apply this phrase to your English studies: simply do what feels best, or perhaps feels easiest, or do what just comes natural to you.

Best of luck to you!!!

Go with the flow- having the information you obtained you will be in a good position to deal with any possible variable or circumstance.
