Class preparation involves regularly dedicating time to complete readings, labs, group work and other class activities. A starting point is to block out at least one to two hours of preparation time for each hour you spend in class. Everyone is different, so adjust as you go.
You may already feel like you have more control just by clarifying how you spend your time. You may also wish to incorporate your weekly personal academic schedule into your yearly agenda or calendar, blocking off these times for the entire term. If you’re using an online calendar, such as Google Calendar or Microsoft Outlook, use the recurring event feature.
