Final exam season can feel overwhelming, for both teachers and students. After months of teaching content, it’s tempting to think the only responsible thing to do is review everything. Plus your students will likely give you that same impression. “We learned that 10 months ago, and you expect me to remember it?”
But trying to review an entire year of chemistry in a few class periods rarely works well. Students feel rushed, the review becomes surface-level, and the most important concepts don’t get the attention they need. In order to be effective, final exam review should be strategic.
In this post, I’ll walk through a simple framework for deciding what to review and what to skip, so your review time actually helps students succeed. Because it really should be different year to year, and based on the students in your classroom.
Why You Shouldn’t Review Everything
The biggest mistake teachers make with final exam review is trying to cover every unit from the entire year. But the reality is, not every topic needs review. There are three categories of content that usually don’t need much class time.
1. Concepts That Are Too Basic
Some early topics simply become foundational skills that students use all year long. Your students don’t need this review from you. If they need it, they should get this review on their own. Things that come to mind are, metric conversions, lab safety, atomic structure, and reading the periodic table.
Even if you didn’t integrate spiral review, students have practiced these skills repeatedly throughout the year. That happens by default. Chemistry requires these skills to be practiced all year. Spending precious review time on them often isn’t the best use of class time.
2. Concepts Students Already Understand Well
Sometimes a unit just went really well. If your students mastered dimensional analysis, or they nailed the mole concept you should not be spending time reviewing this. If most students performed well on a test and demonstrated they actually understand content you don’t need to review it. This is especially true if it’s a skill that continued to pop up during the remainder of the course. Nomenclature comes to mind. Once it’s learned, students use it all year long. There’s no way they did well, and forgot it all by the end of the year. On the other hand, acids and bases might not be in this category. They may have understood the first time, but didn’t get a lot of continued practice, so a quick refresher would likely suffice.
3. Content Students Can Easily Review Independently
There are also topics that students may not remember perfectly, but they’re straightforward enough to review on their own. This is one of the many reasons I love building interactive notebooks with guided notes. Things that come to mind here are vocabulary-heavy topics (phase of matter, physical and chemical changes), memorizing formulas, and basic concept recall. Ensure your students know how to study on their own. They should be able to handle these easier topics on their own.
Let Your Test Data Guide Your Review
Instead of guessing what students need, one of the best things you can do is look at your assessment data from the year. Go back through your unit tests and ask:
- Which units had the lowest class averages?
- Which concepts required the most reteaching?
- Where did students struggle the most?
Those are the topics most likely to show up as weak points again on the final exam. For many chemistry teachers, the biggest struggle areas tend to stoichiometry, gas laws, solutions, kinetics, and redox. These topics often require multi-step reasoning, and a deep understanding of multiple concepts in chemistry which makes them much harder for students to retain months later. The topics were tough for them the first time around, and they also will review many topics all at once. This is where structured review activities are most valuable!
A Simple Strategy: Review the “Big Thinking” Units
Another helpful rule of thumb is to focus your review on the units that required the most problem-solving and conceptual thinking.
For example, understanding potential energy diagrams requires students to:
- read chemical reactions
- understand Collision Theory
- differentiate between endothermic and exothermic
- understand heat of reaction/enthalpy
- calculate enthalpy
- convert between joules and kilojoules
- manipulate enthalpy (Hess’s Law)
- have an understanding of moles as a way to group atoms/molecules
and I’m sure I could come up with 5 more if I took the time.
Finding those heavy hitters will help your students the most. Simpler topics like naming compounds or identifying phases of matter often come back quickly with minimal review. Make sure to invest your time wisely.
Let Students Use Their Own Data
One of my favorite strategies for final exam preparation is giving students a way to analyze their own performance data (you know I love self assessment!) In my classroom, students use a test score tracker where they graph their scores from each unit test throughout the year.
When it’s time to prepare for the final exam, this becomes incredibly valuable. Students can look at their graph and immediately see patterns:
- Which units they did well on
- Which units they struggled with
- Where their performance improved over time
From there, students can decide which units they personally need to review. This gives them ownership over their studying and helps prevent the “study everything the night before” approach that rarely works. If you haven’t been using a test score tracker for the whole year, you can usually still get the data together. Just go into your gradebook and print progress reports. You should be able to filter TESTS for the FULL YEAR. Then print them out and distribute them to your students. That’s effectively the data table that will form the graph.
Remember That Understanding Can Improve Later
Another important thing to keep in mind is that students sometimes learn concepts better later in the year. A student might struggle with atomic structure early in the year, but after learning about the periodic table and bonding, the ideas finally click. If you only look at the original test score, it might seem like atomic structure needs heavy review even though the student now understands it. This is why I allow my students to retake tests. But when they do, they must plot the retake on their test score tracker as well as the original score.
One way to check for this is to give students a short benchmark or practice final exam before your review days. This gives you new data showing what students currently understand. If you’d like something ready to go, I have a final exam / benchmark practice test available that teachers can use to quickly collect this type of data before beginning their review. There’s a companion document that connects each question to a unit of study, so when students get their tests back, they know EXACTLY which lessons and units need their attention. You could even graph this data on the test score tracker as well.
Add Some Student Choice
Review is most effective when students feel like the work is relevant to their own needs. Instead of assigning the same review packet to every student, consider building in some choice. Students should choose two or three units to focus on based on their test score tracker.
You might set up:
- Review stations for different units
- Choice boards with different topic reviews
- Small group practice based on similar struggles
This allows students to spend more time practicing what they actually need. Read more about ways that you can review with your students without adding anything new. I really like to break out old stuff and do it again. There’s no need to create 16 different review activities for each unit of chemistry.
Final Exam Review Should Be Targeted
The goal of review isn’t to reteach the entire course. It’s to help students reconnect with the most challenging ideas and give them the confidence to apply what they’ve learned. In total, you should be targeting review using assessment data, student reflection, and bringing back heavy hitters. Make sure to use that limited review time wisely before your students showcase all they’ve learned!
