Your grade is 88% and the final counts for 30% of it. To reach your 90% target, you need 94.67% on the final.

How it works

Score needed on the final = (target − current × (1 − w)) / w

Score needed = (target − current × (1 − w)) ÷ w, where w is the final's weight as a fraction (e.g. 30% → 0.3).

What is this tool?

As the end of term approaches, every student wants to know one thing: what score do I need on the final to reach my target grade? This tool answers exactly that. Enter your current grade, how much the final counts toward your overall grade, and the final grade you're aiming for — it works backward to the score you need on the exam. The other mode goes the other way: type in a final score you think you can earn, and it predicts your overall grade. You can instantly see whether one more push will lift you to the next band, or whether your target is already locked in — which helps you decide where to spend your limited study time.

How to use it

Find the score you need: 1. Choose the 'Score I need' tab. 2. Enter your current grade, the final's weight, and your target grade — all as percentages. 3. The score you need on the final appears instantly, color-coded by how achievable it is (comfortable, effort needed, not possible, or already secured). Predict your final grade: 1. Switch to the 'Predict my grade' tab. 2. Enter your current grade, the score you expect on the final, and the final's weight. 3. See your final grade along with a breakdown of the locked-in part and the final's contribution.

Formula and definition

Score needed: needed = (target − current × (1 − w)) ÷ w where w is the final's weight as a fraction (e.g. 30% → w = 0.3). Example: current 88%, final weight 30%, target 90% → (90 − 88×0.7) ÷ 0.3 ≈ 94.7%. Final grade: final = current × (1 − w) + final score × w Example: current 80%, final 90%, final weight 30% → 80×0.7 + 90×0.3 = 83%.

Reading your results

A needed score between 0 and 100 is achievable. Above 100% means the target is out of reach even with a perfect final — labeled 'not possible.' Lower the target or recheck your inputs. At or below 0% means you've already secured the goal and could score zero on the final and still hit it ('secured'). As a rough guide to difficulty, a needed score of 70 or less is 'comfortable' and above 70 is 'effort needed.' These are only guides — confirm grade cutoffs with your school's official policy.

Frequently asked questions

What is a grade weight? ▾

A weight is the share of your final grade that an exam or assignment is worth. If the final is weighted 30%, it determines 30% of your overall grade, while everything before it determines the other 70%. The larger the weight, the more that piece moves your grade.

What if it says I need more than 100%? ▾

That means the target is 'not possible' — even a perfect score on the final won't be enough. Lower your target to a realistic value, or double-check that your current grade and the final's weight are entered correctly. It may also be worth asking your teacher about extra credit or reassessment.

How do I work out my current grade? ▾

Your current grade is the weighted average of everything before the final — assignments, quizzes, and midterms, each scaled by its own weight. Our Grade Calculator lets you enter each item's score and weight to compute your current grade quickly.

What is a weighted average? ▾

A weighted average multiplies each score by its weight, sums them, and divides by the total weight. Unlike a simple average that treats every score equally, a weighted average lets heavily weighted exams influence the result more. Your final grade is this weighted average.

How do I make sure I pass (secure my target)? ▾

Set your target to the minimum grade you need to pass, then check the score required on the final. Give yourself a small buffer above that number when you plan your studying. Because a high-weight final swings your grade the most, focus first on the subjects where the final counts most.
