First things first; start with the basics and set your study goals. Ask yourself why you are here, at university, possibly (like me) having travelled across the world for this opportunity.
What do you want to achieve in 2019? Is it a new skill you want to gain? Or master a new language? Or boost your career skills to land your dream job? Setting the right goals gives you clarity on what you want to achieve and why you want to achieve it.
Spend some time exploring different categories to find your area of interest and narrow down your choices to a few courses. Read the course descriptions to understand what the courses are about and choose the courses that meet your learning goal.
Being confused with your interested subject to read about will not help you to have the joy of learning. therefore make sure you have choosen the right course you enjoy studying about.
If you have a long night of studying ahead of you, make a plan for the day. Aim to work for 30-60 minute periods with 5-10 minute breaks in between. Your brain needs the break to recharge.
Try to switch subjects every hour or so, too, to prevent yourself from getting bored and saturating your mind. Too much of one subject and your brain will start going on autopilot. A new subject will wake up your mind and your motivation.
