Predicted Grade Calculator
See what GCSE or A Level grade your teacher is likely to predict based on your mocks, classwork, and assessments.
Add any tests, homework marks, or in-class grades your teacher has recorded.
Teachers often adjust predictions slightly. Use 0 for no adjustment. Positive means they predict higher, negative means lower.
How Predicted Grades Are Calculated
A predicted grade is a teacher’s informed estimate of what grade a student will achieve in their final exam. It is not random. Teachers follow a structured mental process that this calculator replicates mathematically.
Weighted Score = Sum of (Grade % x Weight) for each result
Total Weight = Sum of all weights
Weighted Average = Weighted Score / Total Weight
// Step 2: Convert to a grade
Base Grade = Grade Scale lookup(Weighted Average %)
// Step 3: Apply teacher adjustment
Predicted Grade = Base Grade adjusted by +/- N grades
// Example: Two mocks at 65% and 70%, classwork at 72%
Weighted avg = (65×50 + 70×30 + 72×20) / 100 = 68.4%
Base grade = GCSE 6 or A Level B
With +1 teacher uplift = GCSE 7 or A Level A
What Teachers Actually Consider When Predicting Your Grade
Most teachers in England, Wales, and Northern Ireland follow a similar mental process. It is not just about mock exam scores.
Mock exam performance
Mocks carry the most weight. They simulate the real exam conditions most closely and give teachers the clearest signal of how a student will perform on the day. A strong mock is the single biggest factor pushing a prediction up.
In-class assessments and homework
Regular classroom performance shows consistency. A student who performs well on every small test is seen as a reliable predictor. A student who aced one mock but struggles in class might receive a more cautious prediction.
Trajectory and effort
Teachers look at whether a student is improving. A student who scored Grade 4 in their first mock and Grade 6 in their second is likely to be predicted a Grade 7, not a 5. Upward trajectory matters enormously.
School-level calibration
Most schools calibrate predicted grades across departments to ensure consistency. A Head of Department may review individual teacher predictions and ask them to justify predictions above or below the mock result. This means the process is more systematic than many students realise.

Predicted Grades and UCAS Applications
UCAS applications for university entry open in Year 13. One of the most critical sections is your predicted A Level grades, which universities use to decide whether to make you a conditional offer. The predicted grade on your UCAS form comes directly from your school, usually submitted by your form tutor or Head of Year alongside your personal statement.
Can you ask your teacher to change a predicted grade?
Yes. You can have a conversation with your teacher if you believe your predicted grade does not reflect your potential. Come with evidence: your mock scores, your improvement trajectory, specific pieces of work you are proud of. Teachers are generally willing to revise predictions upward if you can justify it. What does not work is simply saying “I think I deserve a higher grade.”
What if your predicted grade is lower than your target?
First, check the university’s policy on applicants with lower predictions. Some universities offer contextual admissions and may make offers to students predicted below the standard requirements if they attend a school with historically lower attainment. Second, some universities make offers below the standard requirement if a student can demonstrate strong potential through other means. Third, clearing remains an option after results day if you exceed your prediction.
