When preparing for the Medical College Admission Test (MCAT), how many practice tests should one undertake to ensure optimal readiness and efficacy in performance? Is there a specific number that strikes the perfect balance between comprehensive exposure to the various subjects and the risk of burnout? Should one take into account the intensity of their study schedule or the breadth of content covered in each practice exam?

Furthermore, could the quality of the tests used in review outweigh the quantity? In a landscape filled with numerous resources, is it more advantageous to focus on fewer, high-quality practice tests or to engage with a more extensive array? Ultimately, what methodologies could assist in quantifying a fruitful approach to practice testing in this monumental journey?
