PREDICT YOUR GRADE. OWN THE EXAM.
vrendify.xyz's Grade Predictor runs a full recon on your grade trajectory — calculates the exact score you need on remaining work, and shows how extra credit shifts your final standing. No sign-up. Instant results.

HOW THE MATH WORKS
Both modes use weighted average mathematics. The Grade Predictor solves for the unknown score on your remaining work, while the Improvement mode calculates the net shift when a new assignment is added to the mix.
STRATEGIC GRADE PLANNING
Use these tools at midterm to map the second half of your semester, before final registration to know what's achievable, and when evaluating extra credit to see if the effort matches the grade payoff.
ZERO DATA TRANSMITTED
Every calculation runs entirely inside your browser. No grade data is ever sent to any server. Your academic standing stays completely private — always.
UNDERSTANDING GRADE CALCULATIONS
Grade Predictor: Mapping the Required Score
The Grade Predictor answers the question every student faces mid-semester: "What score do I need on my remaining work?" It accounts for how much of the course is already graded and how much weight the upcoming assignments carry.
The logic: calculate how many grade points you have already earned, subtract that from your target total, and divide the remainder by the weight of upcoming work. The result is the exact percentage you need to achieve your goal — no guessing required.
Grade Improvement: Evaluating Extra Work
The Improvement mode answers a different question: "How will this extra assignment actually move my grade?" This is critical when weighing optional extra credit, makeup exams, or retakes.
It calculates what portion of your grade remains unchanged and what portion gets replaced by the new work. Combining both portions gives a precise projection of your new grade — before you invest the time and effort.
Both modes share the same core principle: grades are weighted averages. Understanding the weighting is the key to every smart academic decision from now until finals.
GRADE CALCULATION FORMULAS
Finding Your Required Score
Current Grade: Your average on completed work (85% → 0.85)
Completed Weight: Weight of graded work as a decimal (70% → 0.70)
Remaining Weight: Weight of upcoming work as a decimal (30% → 0.30)
Calculating Grade After New Assignment
Unchanged Weight: 1 minus the new assignment weight (100% − 10% = 90% → 0.90)
Expected Score: Grade anticipated on the new assignment (95% → 0.95)
New Assignment Weight: Contribution of the extra work (10% → 0.10)
Always convert all percentages to decimal form before calculating.

MAKING SMART ACADEMIC DECISIONS
Grade predictions are not just numbers — they are the intelligence you need to allocate study time effectively, set realistic targets, and have honest conversations with instructors before it is too late.
When Grade Analysis Matters Most
Several moments in the semester call for a hard look at your numbers:
- At midterm — assess your standing before the second half begins
- Before final exam registration deadlines — know if your target is achievable
- When extra credit surfaces — evaluate whether the effort justifies the grade shift
- At scholarship renewal periods — know exactly what you need to maintain funding
- Before withdrawal deadlines — base the decision on math, not anxiety
SEMESTER PLANNING EXAMPLE
Sarah is taking psychology with this structure: quizzes 15%, research paper 25%, midterm 30%, final 30%. Her current grades: quizzes 92%, paper 84%, midterm 76%.
Weighted earned: (0.92 × 0.15) + (0.84 × 0.25) + (0.76 × 0.30) = 0.138 + 0.210 + 0.228 = 57.6 points out of 70 possible so far.
- Total points needed: 87
- Points already earned: 57.6
- Points needed from final: 87 − 57.6 = 29.4
- Required final score: 29.4 ÷ 0.30 = 98% — extremely difficult
- B (83%) requires 84.7% on the final — challenging but achievable
- Ask about extra credit to recover lost points from the midterm
- Focus prep time on high-weight final exam topics
This analysis converts anxiety into a concrete action plan — and makes advisor meetings far more productive.
Interpreting Your Results
Know what the output actually means before you react to it:
- Required score above 100% — your current target may need adjusting; explore extra credit
- 95–100% required — near-perfect performance needed; plan accordingly
- 85–94% required — challenging but achievable with focused preparation
- Below your current average — you are already on track; maintain your effort
For improvement calculations: changes under 0.5% rarely justify major time investment unless they push you across a letter-grade boundary. Gains of 1–2% are meaningful. Gains above 3% can significantly shift your academic standing.
Always verify weights against your course syllabus. Small errors in weight input can meaningfully affect results. When in doubt, use conservative (slightly lower) estimates for your current grade to give yourself a safer planning margin.
