Calm down. First, it is IMPOSSIBLE to stay focused for 10 hours a day so don't even attempt. I would say three hours a day (WITH PLENTY OF BREAKS) is the best amount if you're so determined. You have a life to live and you will stress yourself out too much. Being stress free is a part of preparing for exams. You have 10 months. Create a study schedule. Use the weekdays with 3 hours to prepare for the harder subjects and weekends and 1.5 hour to prepare for easier subjects. Nobody has to study 10 hours a day. Not even those in medical school. Continuous practice and trying to see how ideas relate to everyday life will really help. Think of some weird connections to help remember a concept. I'm not sure what these tests are for and why you're taking them but just relax. Honestly.
