IB Predicted Grades Demystified: Your Ultimate Guide
Learn how IB predicted grades work and why they're vital for university offers. Understand the role of mock exams and IAs, and discover what steps you can take.
IB Predicted Grades Demystified: Your Ultimate Guide
Let's talk about one of the most stressful parts of DP2: predicted grades. It can feel like your entire future is being decided by a number your teacher comes up with months before your final exams. And while they are super important, they aren't the final word on your ability or your university prospects.
Think of this guide as a chat with your tutor. We're going to break down exactly what predicted grades are, how they're decided, and most importantly, what you can actually do to influence them and how to react if they’re not what you hoped for.
Part 1: So, What's the Big Deal with Predicted Grades?
Simply put, a predicted grade is your teacher's professional, evidence-based estimate of the final grade you'll achieve in their subject. Because most university applications are due long before your final IB exams, these predictions are the main academic data universities use to assess you.
- University Admissions: This is the big one. Universities use your predicted grades to gauge if you're a good academic fit for their courses.
- Conditional Offers: For many universities, especially in the UK and Europe, your offer will be "conditional" on you achieving a certain score in your final exams. Predicted grades are what get you that conditional offer in the first place.
- Academic Feedback: They act as a crucial check-in, showing you where you're tracking and which subjects might need more focus before the final push.
How Universities See Your Predictions: A Global Snapshot
Not all universities treat predicted grades the same way. It's crucial to know how your target region views them.
| Region | How Predicted Grades Are Used |
|---|---|
| UK & Europe | Heavily relied upon. They are the primary academic tool for making conditional offers. For top unis like Oxbridge, you'll need predictions in the 38-45 point range, with specific 7s in your HLs. |
| United States | Part of a "holistic" review. They are important, but considered alongside your GPA, essays, recommendations, and extracurriculars. Strong predictions support your application, but they won't make or break it on their own. |
| Canada | A key factor. Canadian universities use them to make conditional offers, similar to the UK system. |
Part 2: The Formula: How Are Your Predicted Grades Calculated?
Your teachers don't just pick a number out of thin air. They act like detectives, gathering evidence from your entire time in the DP. The goal is to be as accurate as possible, and they base their judgment on a few key pieces of evidence:
1. Mock Exams
This is often the heavyweight champion of prediction factors. Mocks are designed to simulate the real thing, so a strong performance here is the best evidence you can provide that you're capable of getting a top grade.
2. Internal Assessments (IAs)
The quality of your IA drafts and your final submitted piece is a huge indicator of your skill. It's a major project that directly contributes to your final grade, so it heavily influences your teacher's prediction.
3. Consistent Performance
Your grades in class tests, essays, and assignments throughout DP1 and DP2 matter. Teachers look at your trajectory – are you improving? Are you consistent? This body of work paints a picture of your work ethic and understanding.
4. Engagement & Participation
While not a direct calculation, your attitude matters. A student who actively participates, asks thoughtful questions, and seeks feedback shows a commitment that teachers notice and factor into their professional judgment.
Part 3: The Game Plan: How to Positively Influence Your Predictions
Okay, so you're not a passive bystander in this process. You have agency. Here’s how to build a strong case for the grades you want:
- Start Your IAs Early: Don't leave them to the last minute. Give yourself time to draft, get feedback, and refine your work. A polished IA is a guaranteed way to impress.
- Create a Mock Exam Revision Plan: Work backwards from your mock exam dates. Do past papers under timed conditions. Identify your weak spots and tackle them head-on. Don't just cram.
- Communicate with Your Teachers: If you're struggling with a topic, ask for help. If you want to know how to improve, ask for specific feedback. This shows initiative and a desire to succeed.
- Sweat the Small Stuff: Hand in homework on time. Prepare for your regular class tests. Consistency builds trust and demonstrates you're a serious student.
Part 4: "I'm Not Happy With My Predictions"—What Now?
It’s a gut punch to see a predicted grade that’s lower than what you need or what you feel you deserve. It's okay to be disappointed, but it's not the end of the road. Here is a productive, step-by-step approach to handle it.
- Stay Calm and Avoid Pleading: Your teacher has made a professional judgment based on evidence. Approaching them emotionally or demanding a change is the fastest way to shut down the conversation.
- Schedule a Meeting: Ask for a 15-minute meeting to discuss your grade. This is respectful of their time and shows you are taking this seriously.
- Come Prepared with Evidence: Gather your recent tests, strong essays, or an improved IA draft. The goal is to build a case that your recent performance suggests a higher potential than your past record.
- Ask the Right Question: Instead of "Can you please change my grade?", ask: "What evidence would I need to show you over the next few weeks to give you the confidence to reconsider my prediction before the final deadline?" This transforms the conversation from a confrontation into a collaboration.
- Focus on the Final Exams: This is the most important step. A predicted grade is an estimate. Your final exam is a fact. Universities, especially if you narrowly miss a conditional offer, will look at your final results. Outperforming your prediction is the ultimate proof of your ability. Use a disappointing grade as fuel to power your revision.

Hi, I’m Manmohini, an IB graduate with 40 points, now studying International Relations and Global Affairs in Italy. I earned 7s in HL History and HL English A, along with an A in TOK, and I’ve been tutoring these subjects for around four years. My experience working with organisations like NATO and the United Nations has deepened my understanding of global issues — something I love bringing into my lessons to make learning more relevant and thought-provoking. I focus on helping students see connections between ideas, develop strong essay and critical thinking skills, and approach the IB with confidence and curiosity rather than stress. My lessons are interactive and tailored to each student’s goals, whether that’s improving analysis, refining writing, or mastering exam techniques. I see tutoring as more than academics — it’s about building perspective and empowering students to express themselves clearly while staying balanced.. When I’m not tutoring, you’ll usually find me hiking, playing new music, or planning my next travel adventure.
Why Lanterna?
IB predicted grades are your teachers' official estimates of your final IB exam scores. They are crucial because many universities, especially in the UK and Europe, use them to make conditional offers of admission before your final results are released. Strong predicted grades are often essential to be considered for competitive courses.
You can positively influence your predicted grades by consistently performing well in class, excelling in mock exams, and submitting high-quality Internal Assessments (IAs). Teachers look for evidence of your potential, so treating mocks and IAs with the seriousness of final exams is key. A Lanterna tutor can provide expert guidance to help you master your subjects and boost your performance on these key assessments.
First, schedule a calm conversation with your teachers to understand their reasoning and ask what specific improvements are needed. Focus on excelling in your upcoming assessments to demonstrate your capabilities. For a structured approach, a free IB consultation with Lanterna can provide a clear, personalised plan to help you strengthen your academic profile and get back on track.
The Lanterna IB consultation is a free, 20–30 minute online call with a Student Success Expert. It’s an opportunity for students and parents to discuss specific IB challenges, such as predicted grades or university applications, and receive a personalised action plan to achieve their goals.
Yes, completely free. The 20-30 minute consultation is designed to provide genuine value and clarity on your IB journey. There is no obligation to purchase tutoring afterwards; our goal is to help you identify your priorities and next steps for success.
Historically, there's often a discrepancy. Only about 50-60% of predicted grades exactly match final results, with over-prediction being more common than under-prediction. This is why focusing on your final exams is crucial, as your actual results determine whether you meet university offer conditions. Lanterna's tutors can help you build a solid revision strategy to ensure your final grades reflect your true ability.
Our Student Success Experts are IB specialists who have extensive experience guiding families through the Diploma Programme. They are not tutors, but rather academic advisors who help you understand your challenges, set goals, and create a strategic plan, whether it's for improving predicted grades, managing IAs, or preparing for final exams.
Absolutely. Our tutors are all high-achieving IB graduates (scoring 40+ points) who are experts in their subjects. They provide one-on-one, personalised support to help you master difficult concepts, refine your exam technique, and build the confidence needed to turn your predicted grades into reality for any IB subject, at SL or HL.
After the call, you will have a clear understanding of your academic priorities and a concrete plan of action. If you decide that tutoring would be beneficial, your Student Success Expert will match you with the perfect tutor for your needs. If not, you are free to use the insights and plan from the consultation on your own. There is no pressure or obligation.
While it varies by school, official predicted grades are typically finalised and submitted to universities between September and October of your second IB year (DP2). This timeline is designed to align with major university application deadlines, like UCAS in the UK.
