Having a personal MCAT trainer is not strictly necessary, but it can be highly beneficial for students who need structure, accountability, or tailored strategies. One-on-one guidance helps identify weaknesses, customize study plans, and provide immediate feedback. Students can decide if a personal trainer is worth it by assessing their self-discipline, consistency, and ability to identify and address gaps on their own. If self-study has led to plateaued practice scores or persistent confusion in key subjects, personalized coaching can often accelerate progress and improve confidence.
