Shhhhhh about to tell you a med school secret........
Grades don't matter that much!
And by don't matter I don't mean like hey bro tank all you exams, get 70s on them and life is fine. But like to get an A you going to need generally 90% or better, even with the 10% clicker grade it takes a lot of time studying to get an A (5 -7 wrong per an exam of 75-90 questions). Now, the range for a B is so big (89%-75%) that its very hard to get a C. There are no +/- grades, so the person who gets 15 wrong on the exam will end up with the same final letter grade as a person who gets 6 wrong on the exams. The "B" at Touro is similar to the "Pass" grade at other medical schools. The consensus from years above us at Touro, and other medical schools, is that pre-clinical grades don't matter too much, only board scores do, so your statement about 10% costing you a residency spot is insane.
Let's do a thought experiment. Student 1 has a 4.0 in the Touro system, he crams and absconds himself to the library at all hours of the day/weekend, but due to the crazy schedule of medical school the cramming for the exams do not help with long term understanding, worse he burns himself out midway through his 2nd year, never letting go of his desire to keep the perfect GPA. By the time Board dedicated study period comes he cannot keep his eyes open. Student 1 scores a 218 on Step 1.
Student 2 has a 3.5 GPA in the Touro system. She focuses on long term understanding and lives a life of structured discipline, allowing for time with friends and hobbies. She works hard, but is focused on really understanding the material and stops to think frequently about the clinical applications. Due to this though occasionally student 2 misses a minor detail question on the exam, causing her to end up with B's in a few classes, but come time for her dedicated study period for Boards she is fresh. This student scores a 240 on Step 1.
TL;DR Grades don't matter that much. Focus on understanding the material and staying sane long term, don't jump off the roof because you got an 87 or and 89, or even an 80. DO NOT underestimate the step. With that being said, if score less than 80%-85% on an exam your study method is wrong, but again no worries just fix it next exam.
