Google Forms is one of the most common quiz tools in school, and most of that use is practice: ungraded self-checks, review guides, and study sets teachers build so you can prep for the real thing. Because a Form runs in a browser tab, the best way to study with AI on a Google Forms practice quiz is to keep Lensia's sidebar chat open right next to it. Attempt each question yourself, then talk it through in the sidebar: paste what you tried, ask why you were off, ask for a similar problem to test the idea again. When one question stops you cold and you just want it explained on the spot, the floating panel is a keystroke away. Install Lensia free and study a Form the way you would with a patient tutor sitting next to you.
A note up front: this guide is about practice and review material, not live graded work. Using any AI tool during a graded assessment where AI is restricted is academic dishonesty. Use Lensia to learn the material so you can answer the graded version on your own.
Start in the sidebar chat
The sidebar is the main way to use Lensia on a practice Form, and it is on every plan. Open it by clicking the Lensia icon in your Chrome toolbar. A chat opens in Chrome's side panel, docked next to your Form so the questions and the conversation stay side by side.
Why the sidebar fits a study session better than a one-off answer: it keeps the whole thread. You can work through a ten-question review Form without losing the thread of what you have already covered.
- Conversation history stays put between sessions, so tomorrow you can scroll back to the questions you missed today and re-test yourself.
- Bookmarks let you save the explanations you want to reread the night before the graded quiz.
- A model picker sits at the top of the chat. Run quick recall questions on a fast model, then switch to Claude Sonnet 5 mid-thread when a chemistry item needs more careful reasoning, all in the same conversation.
A good loop on a practice Form: read the question, commit to your own answer, then type it into the sidebar and ask Lensia to check your reasoning. When you miss one, ask it to generate two or three similar questions on the same concept and attempt those cold. Re-deriving the idea is what makes it stick. For the full tour of the sidebar and the capture panel, read how Lensia works.
What paid tiers add in the sidebar
The sidebar itself is free. On Basic and up, the AI can run a web search or fetch a URL mid-chat, so if a practice question references something your notes do not cover, it can pull the definition or formula into the explanation. On Pro, agent mode lets the AI chain several steps inside the sidebar, like reading the notes open in another tab before it answers.
Grab a question fast with the floating panel
Sometimes you do not want to retype a question at all, especially a dense science problem with numbers and units. That is what the floating panel is for, and it works on every plan. Press Ctrl+Shift+X, drag a box around the question and all its answer choices, and a worked explanation floats up on top of the Form in under three seconds. The page stays visible underneath, so you can check the explanation against your own attempt without leaving the quiz.
The panel has a second mode too. Flip on Ask Mode and it becomes a custom-question box: type your own prompt and attach up to three images from your screen, which is handy when a question spans a diagram plus a passage. Two shortcuts keep it quick:
Ctrl+Shift+Frepeats your last capture area, so a Form full of same-shaped questions takes one keypress each.Ctrl+Shift+Ehides the panel entirely and brings it back.
If it reads cleanly, only that text goes to the AI and the image stays on your device.
Question types and how to study each
Multiple choice
The most common format on practice Forms. Pick your own answer first, then either paste the question into the sidebar or capture it. Lensia explains why the right choice holds up and why each wrong option does not. That contrast is usually where the real learning is.
Short answer and paragraph
Attempt a full answer yourself, then hand the prompt to the sidebar. Lensia lays out the core argument and the supporting points so you can see what you left out, then you write the graded version in your own words from understanding.
Dropdown and linear scale
Capture the question with its options or scale labels visible, or describe it in the sidebar. Lensia explains which option fits and what the question is really probing, which helps when you are learning a rubric.
File upload
These ask you to submit your own work. Use the sidebar to understand the underlying concepts and to pressure-test your draft for gaps, but the submission is yours to write.
Subject-specific study tips
- Science and math: capture the full problem with numbers, units, and any graph, or paste it into the sidebar and keep asking follow-ups until the steps make sense. Lensia works through the calculation one step at a time, so you can find exactly where your own work diverged.
- History and social studies: ask in the sidebar for the answer plus the context around it, since the context is what you actually need to remember for the test.
- English and literature: for reading comprehension, capture the question with the excerpt on screen. Lensia walks the reasoning so you can see how a strong reader gets there.
- Foreign language: capture or paste the question in the original language. Lensia reads it and explains the grammar point the item is testing, which is useful for checking your translation.

Plans and pricing
- Free costs nothing; sign in with Google. A starter usage allowance for light review, plus the sidebar chat and Ask Mode.
- Basic gives about 10 times the Free usage, plus reasoning mode, web search, fetch URL, custom instructions, and Advanced models. Enough for a full semester of steady studying.
- Pro has the highest usage allowance and adds agent mode in the sidebar.
A few specifics: Lensia Max auto-picks a fitting Quick or Standard model and takes 15% off the request. Reasoning is a single on/off toggle, not separate levels. Auto-Solve Mode watches a page and answers on its own, but it currently supports Vocabulary.com only, so a Google Forms practice quiz still uses the sidebar or the capture flow. Sign-in is Google only. Compare the plans in the best AI tool for college students guide, or activate a paid plan when you are ready.
Other platforms Lensia works on
Lensia reads from your screen instead of connecting to any one platform, so it helps wherever your course material lives: Canvas, Moodle and Blackboard, and Schoology all have their own guides. One exception: Lensia cannot run inside Respondus LockDown Browser or any locked-down browser application, since Chrome extensions do not load there.
Get started
Install Lensia, sign in with Google, and open the sidebar next to your next practice Form. Work a few questions through it, and reach for Ctrl+Shift+X when you want one explained on the spot. The Free tier costs nothing to start.
