Late at night it is usually more advisable to learn with someone else. This year we have the advantage of having shabbos on erev shevuos so we can all get the decent shluff that we don’t usually get on erev shevuos, plus we have friday night to practice staying awake during learning!!!!!
In England we have only a short night anyway with nacht being so late and alois so early. By the time we daven and have the seuda it leaves only 2-3 hours to learn. Australia have close to 12 hours. I don’t know how long you have on the states. Maybe you can post in which state you live in and how long you have to learn
