How do I decide which assignment to do first when everything is due?

TL;DR: Start with the assignment that is due soonest and costs you the most if you miss it, as long as you can realistically finish it. If two are tied, pick the one that earns more grade per hour of remaining work, and book early time for anything that depends on other people. Then work on one assignment at a time in focused blocks.

I usually had prioritization problems with my university assignments; this system helped me a lot.

What should you do before choosing anything?

Write every assignment down with five facts next to it: the exact deadline, the hours of work left, the grade weight, anything it depends on, and what happens if it's late. Choosing from memory tends to pick whichever task feels loudest, which is often the easiest one.

University study guidance points at the same inputs. The University of Colorado's student life office suggests you "consider upcoming deadlines, how much time each task will take and which assignments may require more preparation."^[1] Deadline matters, but it is one column of several.

A list for a hard week might look like this:

• Stats problem set: due Wednesday at midnight, about 3 hours left, 5% of the grade, no dependencies.
• Reading response: due Wednesday, about 1 hour, pass or fail.
• History essay: due Thursday at 9am, about 5 hours left, 20% of the grade, needs two library books.
• Lab report: due Friday, about 4 hours left, 15% of the grade, needs your partner's data.

Be honest about the hours. If an estimate feels fuzzy, split the assignment into parts and guess minutes for each part. Small guesses add up to a more accurate total than one big guess.

Which assignment goes first?

The one that is both urgent and important. The University of Leeds library guidance puts it in four words: "Important and urgent? Do it now."^[2]

Sheridan College's guidance agrees that tasks due this week should usually come first.^[3] In the example list, that means the stats set and the reading response, both due Wednesday. The reading response is urgent but low stakes, so give it its hour and move on. Most of your Wednesday effort belongs to the stats set.

Check feasibility before you commit. If the nearest assignment cannot be finished in the time left no matter what you do, starting there can burn the hours that would have saved a different grade. In that case, skip ahead to the section on what to do when you can't finish everything.

How do you break a tie between two urgent assignments?

Compare grade weight per hour of remaining work. Divide each assignment's share of the grade by the hours it still needs, and favour the higher number.

In the example, the essay is worth 20% for 5 hours, about 4 points per hour. The lab report is worth 15% for 4 hours, about 3.75 points per hour. Those are close, so other factors decide it. The essay is due a day earlier, and an assignment that is already partly done usually needs fewer hours than you fear.

Use this as a tie-breaker only. It should not override a hard deadline that is hours away, or an assignment with a severe late penalty. A 5% task that gets a zero for being one minute late can outrank a 20% task due in three days.

What about tasks that depend on other people?

Start those first, even when they are due later. Anything that needs a reply from a lab partner, a library request, or a question to your instructor has waiting time built in, and the clock on that wait only starts when you send the message.

The University of Cincinnati's online student guide suggests treating due dates "as anchors, not starting signals."^[4] Plan backward from each due date. For the lab report, that means messaging your partner about the data today, a ten-minute job that unblocks Friday. For the essay, it means requesting the books now so they arrive before Thursday.

Where you can, aim to finish a day early. That spare day covers the things that go wrong at the last minute, like a printer that fails or an instruction you misread.

How do you start when an assignment feels too big to begin?

Turn it into the smallest concrete next action and give that action a time block. Kellogg Community College's study guide recommends breaking assignments into steps or milestones that you can schedule.^[5]

"Write the history essay" is hard to start. "Find two sources for the second paragraph, 25 minutes" is easy to start. Other good next actions:

• Reread the assignment brief and highlight every requirement, 15 minutes.
• Outline the essay in bullet points, 30 minutes.
• Draft the intro paragraph, 45 minutes.
• Check the lab report rubric against what you have, 20 minutes.

When you sit down, the only decision is whether to do the next action. That is a smaller decision than "which of four assignments should I care about right now", and it is easier to make when your attention is unreliable.

Should you switch between assignments to keep them all moving?

Mostly no. Rotating through everything feels productive, but each switch has a cost.

Research on task switching describes a "switch cost": performance gets worse right after you change tasks.^[6] In lab studies, responses are slower and errors are usually more common when the task changes than when the same task repeats.^[7] Some of that cost remains even when people have time to prepare for the switch.^[7] These are controlled experiments with simple tasks, so the size of the effect on an essay is unknown, though the direction is consistent.

In practice, give one assignment a whole block, somewhere between 45 and 90 minutes. Before you stop, write the next action at the top of the document so you can restart without rereading everything. TimeBud's focus timer works this way: it runs through a queue of jobs one at a time, so the next thing is already decided when a block ends.

What if you can't finish everything?

Decide that early, while you still have options. Waiting until the night before removes most of them.

You have three main moves:

• Submit the highest-value work you can finish properly, and accept a lower mark or a miss on the lowest-value item.
• Ask for an extension, ideally days before the deadline with a short, specific reason.
• Ask the instructor whether partial work can earn partial credit.

Does planning like this improve grades?

There is a link, but it is moderate and it is a correlation. A 2026 systematic review and meta-analysis of 31 studies, with 13,506 participants, found that time management is "significantly and moderately positively correlated with college students' learning outcomes (r = 0.250)."^[8]

That finding shows students who manage time well tend to do better. It does not prove that any one ordering method causes better grades. The research mostly studies broad time-management habits and task switching, and it says little about ranking formulas for assignments. Treat the method above as a sensible default based on deadline, importance, effort and dependencies, and adjust it when a rule from your course, like a harsh late penalty, changes the stakes.

If building the list and the next actions is the part you get stuck on, TimeBud breaks each assignment into jobs with minute estimates and dependencies, then fills only the free time in your calendar with them, leaving a buffer after classes and other events.
