By Zayna Dar, Founder, Shuhari Tuition
When it comes to your education, few periods are as stressful as the months and weeks leading up to GCSEs, A levels, or any other major exams. Many students work hard during exam season, yet don’t see the results they hoped for.
As a tutor, I’ve seen the same pattern get repeated time and time again: revising without a clear plan, avoiding tricky topics, or spending hours re-reading notes without fully absorbing the material. The good news is that with the right strategies in place, students can make their revision far less stressful and ultimately more productive.
In this blog, we’ll look at the revision mistakes that hold your teen back and share practical ways to resolve them.
Mistake 1: revising without a clear plan
Without a plan, it’s all too easy to spend an hour on your favourite topic, skip over tricky areas, or jump between subjects without really making any progress. One of the biggest traps that students fall into is sitting down to ‘do some revision’ without a clear plan.
An effective study plan should be realistic and balanced. It ensures that every subject and topic within that subject gets the attention it needs. It also helps spread the workload across a longer time period so your teen’s not cramming everything into the last few days before an exam. By breaking revision into manageable steps, students can see exactly what they’re aiming for each day, which makes revision far less overwhelming.
This is a big focus for us at Shuhari Tuition. We work closely with students to create a personalised study plan that gives them clear direction so that they can use their revision time more effectively. We start with a baseline assessment for each student, which helps us identify which topics need the most attention, then map out a schedule that spreads the workload out and avoids last-minute cramming.
Quick tip: Encourage your teen to build in time for reviewing old topics as well as learning new ones. Revisiting a topic two or three times over a few weeks is far more effective for exam success than trying to condense it all into one session.
Mistake 2: relying only on passive learning
Many students believe that reading through notes or highlighting a textbook counts as ‘effective revision’. While these methods can feel productive, they’re actually passive forms of learning, and they don’t do much to help information stick.
Passive learning tends to lull students into a false sense of security. They recognise the material when they see it, but in an exam, you need to recall and apply that knowledge without prompts. That’s where active learning comes in.
Our tutors use techniques like:
Active recall:
Testing knowledge without looking at notes.
Past paper practice:
Applying skills in the same way they’ll be tested in the exam.
Teaching the material back:
Explaining a topic in their own words as if they were the tutor.
These revision methods help with consolidation of knowledge, which strengthens long-term memory and deepens understanding.
Quick tip: Encourage your teen to swap reading notes for short, focused bursts of active recall. Even five minutes of quizzing themselves can be more effective than half an hour of passive reading.

Mistake 3: ignoring the mark scheme
All too often, students lose marks simply because they haven’t checked their answers against the mark scheme. They might write a strong response but leave out key terminology or essential steps of a process that are outlined in the mark scheme.
Mark schemes are like roadmaps. They reveal exactly what a creditworthy response looks like and how marks are awarded for each question. Cross-referencing your answers with the mark scheme is useful because it shows you precisely how to structure your responses and what details to include and exclude in your answers.
Our tutors regularly work through past papers with students, guiding them on exactly how to approach constructing an answer to unlock top marks. For example, in GCSE biology, using scientific terminology in your response will ‘trigger’ marks and understanding command words like ‘state’, ‘describe’, and ‘explain’ will help you gain maximum credit. Our tutors help students develop their exam technique and build familiarity with the exam format, which are both essential for exam success.
Quick tip: Turn mark schemes into revision tools. After completing a past paper, create flashcards explaining key processes using the points from the mark scheme. This helps reinforce the knowledge and phrasing to use in your answers that examiners are looking for. Check out this blog for more advice on how to use mark schemes to improve your grades.
Mistake 4: leaving weak topics until the end
Students tend to gravitate towards topics they enjoy or find easiest. This is a common mistake. It might work wonders for your confidence, but when the more complex topics get pushed to the bottom of the priority list, they can end up being rushed (or skipped) in the final run-up to exams.
We all know that weaker areas usually need more time and attention. Leaving them until the last minute can cause unnecessary stress and lead to you losing marks in the exam because you didn’t cover the content thoroughly enough.
Our tutors avoid this potential pitfall by identifying your teen’s weaknesses early on in the process so that revision can be targeted from the get-go. As part of the study plan we create for each student we work with, we break down each unit into topics and support students with learning the content in stages so that there’s ample time to consolidate everything without the pressure of a looming exam.
Quick tip: A good way to tackle the tricky stuff is to study it in short, focused sessions. Spending 20-30 minutes a day regularly revisiting hard topics makes them feel far less daunting by the time exams arrive. Make sure you reward yourself after completing a particularly challenging revision session, as this makes it easier to stay motivated when working through difficult topics.
Mistake 5: cramming at the last minute
When an exam is on the horizon, it’s tempting to spend every spare minute revising in a panic. But this is a symptom of poor time management and one of the least effective ways to prepare.
Cramming floods the brain with information in a short space of time, but it doesn’t give enough opportunity for that knowledge to be transferred into your long-term memory. It can also leave you exhausted, stressed, and more likely to make mistakes in the exam itself.
Instead, steady, consistent revision over the span of days or weeks gives the brain time to process and store information. Our tutors encourage students to treat the final days before an exam as a time for spaced repetition, light review, consolidating knowledge, and managing anxiety rather than learning content from scratch.
Quick tip: In the final 24 hours before an important exam, focus on reviewing core concepts and answering some practice questions, but this isn’t the time to be learning new material. Double-check you have all the right equipment you need for the exam and make sure you get at least eight hours of quality sleep the night before so you go into the exam refreshed and well rested.
Mistake 6: ignoring exam technique
Some students know the content inside out, but they still underperform in exams because they haven’t mastered exam technique. Without good exam technique, students risk running into problems like misinterpreting the question or spending too long on a single question at the expense of the rest of the paper.
To combat this, our tutors build exam skills into lessons from the outset instead of introducing them in the lead up to an exam. This means skills like learning how to decode command words and manage your time are woven into lessons from day one. Just like training a muscle, the more consistently a student works on exam skills, the stronger they become, particularly when working under exam pressure.
Quick tip: Encourage your teen to treat some of their revision sessions as mock exams. Become more strategic with revision by removing their notes, setting a timer, and after completing the paper, get them to check their answers against the mark scheme to diagnose their strengths and weaknesses.
Key takeaways
Many students work incredibly hard for their GCSEs and A levels. However, with the stress of exam season and because no one explicitly teaches them how to revise effectively, it’s easy for students to fall into the trap of revising in an unproductive way. Here is a summary of the common revision mistakes that students make and how to avoid them:
Revising without a clear plan: Without a plan, students often end up revising topics randomly or repeatedly focusing on areas they already feel confident in, while neglecting weaker topics that actually need more attention. A structured study plan helps students balance all topics in a unit, focus on weaker areas, and avoid last-minute cramming.
Relying only on passive learning: Passive learning refers to study methods where students take in information without actively engaging with it. Relying only on passive learning can lead to shallow understanding and poor recall under pressure. Active recall, past paper practice, and teaching material aloud are far more effective revision methods than just re-reading your notes or highlighting a textbook.
Ignoring the mark scheme: Using past papers alongside mark schemes trains students to think like an examiner and understand exactly what they’re looking for. Our tutors will make sure that your teen is very familiar with how marks are awarded and what separates a weak response from a top-band response.
Leaving weak topics until the end: Tackle challenging topics early in the revision process. By getting difficult topics out the way, it reduces the mental weight hanging over you and helps you build momentum. Once the hardest part is done, the rest becomes easier.
Cramming at the last minute: Last-minute cramming is ineffective because information learned quickly is often forgotten quickly. The brain remembers material better when it’s reviewed over time. This strategy is called spaced repetition, where you study smaller amounts regularly over several days or weeks, leading to long-term retention.
Ignoring exam technique: Neglecting exam technique is a common reason students underperform even when they know the material. Exam success isn’t just about what you know, but about how you word your answers. Knowing what command words are asking you to do, managing your time effectively, and structuring your answers properly are all key to performing well in exams.
