Bolded is correct. 90% of people won't be in the top 10%.
The rest is anecdotal, and probably useless for OP.
Anecdotal, yes. Not necessarily useless. Sometimes a subjective perspective is more useful than an objective one. While objectively it makes no sense to "plan" on being in the top 10%, someone who subjectively is willing to both work extremely hard (we're talking 5-6 hours a day outside of class) and creatively can be successful. Think going beyond LEEWS and outlining.
For example, on my torts exam which was open book, I made a prose style outline where I had large chunks of law in exactly the format and phraseology that best conveyed mastery of the material. I could just go through the exam, spot torts, drop my pre-drafted chunks explaining the law then follow up with fact application. If OP is smart enough and dedicated enough to make it happen - he can. Sometimes I think it may be best to ignore what happens to the majority of people and just rock the fuck out of law school. It's really not that hard if you're willing to put in the time and if you can convince yourself that it's fun.
