I was preoccupied with a long daily commute that took hours each week, which I felt could be better spent studying for my Network+ certification Reading a book on the train was challenging, but I learnt that I could use my phone to rapidly complete CompTIA Practice Questions while travelling This style of active recall was transformative; instead of trying to memorise dry lists, I was continually applying information, which revealed that I was frequently mixing up the functions of critical TCP and UDP ports By focussing my commute-time tests entirely on these weak areas, I was able to transform wasted travel time into my most effective study period, consolidating the precise details I needed to recall immediately on exam day
