#1 Embrace variety: instead of solely focusing on one topic, study various topics during a single session. Jot down thoughts on a Post-it Super Sticky Notes to keep ideas close at hand and trade topics every 15 minutes or so.
#2 Drop the highlighters. Evidence shows that highlighting and underlining is largely ineffective. Instead, mark important ideas with Post-it® Arrow Flags and refer to as necessary.
#3 Study with less stuff. Keep your space tidy and organized and only have the materials you need to keep your brain focused.
#4 Get some sleep! The exhaustive effects of an all-nighter can affect your thinking for the next four days! In other words, get some sleep and keep your brain sharp instead of strung out.
