Are you preparing to take the Geometry Regents exam? We know it can be daunting to craft your own study plan, especially when you’re in a time crunch.

That’s why we’ve taken out all of the guesswork in this detailed, 1-month Geometry Regents study guide. With just 30 days, you have enough time to memorize the terms, practice the skills, and understand the concepts you need to ace the Geometry Regents test. 

Our expert study guide is based on our analysis of released Regents exams and the standards and topics that appear most frequently. We’ll cover what to study to get the most bang for your buck. 

First, we recommend you check out our Geometry Regents Review Guide and Geometry Regents Study Tips and Tricks. Then, let’s dive in!

Geometry Regents Study Techniques

For first-time test takers and veteran Regents students alike, sometimes deciding how to study can be more difficult than deciding what to study.

Our plan is based on six essential Geometry Regents study techniques that will set you up for success on the exam. Our techniques are simple, straightforward, and easily accessible. Keep reading to learn more! 

1. Learn Geometry Regents vocabulary with a deck of flashcards.

Some of what you’ll need to know for the Geometry Regents exam will be included on the Regents equation sheet that you’ll be able to use during the test. We recommend checking out our Regents Mathematics Reference Sheet Guide for information about and practice with these formulas. 

However, the Geometry Regents exam is full of other terms and formulas that you’ll need to know cold. Building your own flashcard deck is a great way to learn the terms and equations you’ll need for the exam.

In this guide, we’ll highlight the vocabulary-heavy topics with terms and phrases you’ll need to know. It’s up to you to build your flashcard deck (whether online or on physical paper) and study from it!

2. Spend time skill building with Geometry practice problems.

We can boil most review guides down to one simple thing: practice. Completing Geometry Regents practice problems is a crucial part of your study plan!

To best prepare you for the Geometry Regents exam, we’ve highlighted topics you can practice on Albert. With these questions, you’ll get instant feedback and expert explanations. 

Don’t have access to Albert? Don’t sweat it! You can also check out the practice problems from any Geometry textbook or website. We’ve linked to some of our favorite alternatives in the 30-day study guide below. 

3. Try out topic quizzes to target your learning.

We get it — quizzes likely aren’t what you want to do in your free time. However, taking Geometry Regents topic quizzes can help you find your strengths and weaknesses and direct your studying. 

In our study guide, we’ve linked to question sets from some of our favorite websites. To treat these questions like a “quiz,” set a timer and sit down to complete the questions in a quiet, calm environment. Answer all the questions within the allotted time frame and then go back to grade your own work. 

Put on your teacher hat and use your quiz grades to decide what you need to study more. If you do well on a quiz, you can move on with confidence! If you do poorly, you know you need to revisit that day’s study materials in the future.

4. Set yourself up for success with full-length practice exams.

This technique is a no-brainer. Our best Geometry Regents study tip: take the Geometry Regents exam!

The New York State Education Department website includes released exams and scoring guidelines so that you can take the test and grade your own work.

Better yet, Albert has created never-before-seen Geometry Regents practice exams to build your Regents skills. These exams are instantly graded and include detailed explanations for each question so you can see where you went wrong. 

5. Get some Geometry Regents review with our favorite resources.

Unless you’ve somehow memorized your entire Geometry textbook, you’ll benefit from some Geometry Regents review mixed into your study plan.

We’ve set aside days for you to review skills and concepts through online lessons, videos, and activities. We linked our favorite resources in the guide below, but you’re welcome to check out your favorites as well. 

6. Try out CRQ practice problems to get comfortable with constructed responses.

We’ll be honest: we love CRQs. Not only do constructed response questions make up a hefty portion of the credits on the Geometry Regents exam, but they also allow students to earn partial credit!

In the guide below, we’ve highlighted some constructed response questions from released exams on the topics that appear most frequently in the Geometry Regents. Complete the CRQ on a separate piece of paper and then use the relevant rubrics and model response sets to check your work!

Geometry Regents 30-Day Study Guide Daily Details

Week 1

Time to dive into week 1 of your Geometry Regents study plan! Getting started can be the hardest part, so push yourself to build a routine this week. Carve out designated time in your days for your Geometry Regents study sessions.
