Tips & Best Practices

Press F8 early, then solve yourself

Don't wait until you're stuck. Press F8 as soon as the question loads — TestSolve starts working in the background while you read and attempt the question yourself. By the time you've thought through the problem, the AI answer is already on your phone.

This gives you two independent answers to compare. If they match, you can be confident. If they differ, take a moment to check which calculation is right.

Enable Fn Lock so you don't need to press Fn+F8

Most laptops use the F-keys for brightness, volume, etc. by default. This means pressing F8 alone might adjust your volume instead of triggering TestSolve. You need to either hold Fn + F8 every time, or enable Fn Lock once.

We strongly recommend enabling Fn Lock — it makes F8 work with a single press, which is much faster during timed tests.

Ensure the full question and all answers are visible

TestSolve captures exactly what's on your screen. If part of the question or some answer options are cut off or scrolled out of view, the AI can't see them — and may give a wrong or incomplete answer.

Use a single screen only

If you have multiple monitors, TestSolve captures your primary screen. Make sure your test is running on the same screen that TestSolve is set to capture. Using a second monitor for the test while TestSolve runs on the first will result in a blank or wrong capture.

Charts and tables: make sure they're fully visible

Numerical reasoning questions often come with data tables or charts. The AI reads these directly from the screenshot. If the table is partially obscured or the chart legend is cut off, the AI may misread values.

For data interpretation questions, make sure the chart, its axis labels, and the legend are all clearly visible before pressing F8.

If the answer seems off, press F8 again

If the confidence is low (below 80%) or the answer doesn't look right, scroll to make sure the full question and all answers are visible, then press F8 again. The AI makes a fresh attempt with the updated screenshot which often catches errors from the first pass.

Phone placement

Best method: Stand your phone upright directly in front of your laptop screen, with the back of the phone leaning against the display. This way your eyes never leave the screen — even if a webcam is on, you're always looking straight ahead. The answer is right there in your line of sight.

Alternative: Place your phone flat on the desk next to your keyboard, screen facing up. A quick glance down is natural — like checking the time.

Turn your phone's brightness down slightly, enable Do Not Disturb so notifications don't pop up over the answer, and set your phone to never sleep / no screen timeout so the TestSolve page stays on throughout your test. On most phones: Settings → Display → Screen timeout → set to "Never" or the maximum time available.

For timed tests: develop a rhythm

In SHL-style tests with strict time limits per question:

1. Question loads → immediately press F8
2. Read the question while AI works (4-8 seconds)
3. Check your phone for the answer
4. Select the answer and move to next question

This rhythm lets you complete even the hardest numerical reasoning questions in under 15 seconds total.

Phone shows "Connection failed"

This usually means the session expired. Close the page on your phone, open DisplayHelper again on your computer, and scan the new QR code. Sessions expire after 48 hours of inactivity.

F8 doesn't do anything

Check three things:

1. Is DisplayHelper running? (Check your system tray — bottom right of your screen)
2. Is Fn Lock enabled? (See the table above)
3. Is your phone connected? (Should show "Connected" with a green dot)

AI gives a wrong or weird answer

Usually caused by the question not being fully visible. Scroll to show everything, then press F8 again. If the answer options are in a dropdown, open it before capturing.

For abstract/pattern questions: the AI currently scores ~72% on inductive reasoning. If the answer feels wrong, trust your own pattern recognition.

Works great on

• Numerical reasoning — calculations, percentages, data tables, charts
• Verbal reasoning — True/False/Cannot Say, comprehension, critical reasoning
• Logical reasoning — sequences, patterns, rule-based questions
• Situational judgement — SJT scenario questions
• Data interpretation — graphs, bar charts, pie charts with questions

Not designed for games or gamified assessments

Some employers (e.g. Unilever, BCG) use game-based assessments like Pymetrics, Arctic Shores, or Cappfinity immersive scenarios. These involve dragging objects, reacting to animations, or timed mini-games that change every second.

TestSolve captures a single screenshot — it can't interact with or play through a game. If your assessment is game-based, TestSolve won't be able to help with those sections. It will still work on any standard multiple-choice questions that appear in other parts of the same assessment.
