Study Strategy
Know your numbers.
Own your results.
Check your syllabus weights on day one
Your syllabus tells you exactly how each assignment is weighted. Students who read it on day one can strategically allocate study time — spending more energy on the 40% exam.
Set a target grade, not just "do my best"
Vague goals lead to vague results. Set a specific target (e.g. 82%) and use the Final Grade Calculator to work backwards — finding the exact score you need on each remaining assessment.
Recalculate after every graded assignment
Don't wait until the end of semester. After every grade comes back, update your calculator. You'll know immediately whether you're on track or need to adjust your effort.
A bad early grade isn't a death sentence
Early assignments are often weighted lower. A 55% on a 10% assignment only drops your total by 4.5 points. Run the numbers — you might be much closer to your target than the bad grade feels.
Use the "What do I need?" tool strategically
If you need above 100% on your final, start talking to your professor now about extra credit or marking adjustments. Knowing early gives you options that waiting until the day before won't.
Study smarter, not just harder
Putting in more hours isn't always the answer. The students who move the needle combine time with method — active recall, spaced repetition, and practice tests. That's where Duetoday comes in.

Frequently Asked Questions
How is weighted average calculated?
A weighted average multiplies each assignment's percentage score by its weight, sums those products, then divides by the total weight:
Weighted Average = Σ (Score / Max × Weight) / Σ Weight × 100
For example: 80/100 on a 30% midterm and 90/100 on a 70% final = (0.80 × 30 + 0.90 × 70) / 100 = 87%.
What's the difference between weighted and unweighted GPA?
Unweighted GPA treats every course equally (A = 4.0 regardless of difficulty, max 4.0). Weighted GPA gives extra points for harder courses (AP, IB, honours) — a 4.0 unweighted can become a 5.0 weighted. Most universities recalculate GPA on their own scale during admissions.
What if I don't know all my assignment weights yet?
Check your course syllabus first — instructors are required to publish grading breakdowns at the start of term. If weights are missing, set all weights to 1 for a simple unweighted average of what you have so far.
What if I need more than 100% on my final?
Act now rather than waiting. Ask your professor about extra credit, check whether any assignments can be regraded, and consider adjusting your target grade. Knowing early — even bad news — gives you options that panic the night before won't.
