AI That Solves Practice Tests
Not just the answer — why each option is wrong. Elimination logic + topic review + similar questions.
Ryna AI Editorial Team · Updated 27.04.2026
In Türkiye's TYT exam you get 165 minutes for 120 questions — about 80 seconds each. At that pace, students usually lose points not from not knowing the topic, but from falling for the distractor: two of the options look reasonable, you pick 'B', the answer key says 'C', and that one-letter key never tells you why B was wrong. That gap is what makes you repeat the same mistake across mock exam after mock exam.
Ryna AI is built to close exactly that gap. Paste the test question with all its options (A-E); Ryna gives the correct answer, but the real value is that it explains why each of the other four options is wrong, one by one — 'C states a supporting idea, not the main point', 'D is numerically close but has a unit error'. Turkish reading comprehension, history, geography, biology, physics, chemistry, math — whatever the subject, it runs the same distractor analysis. On the Plus plan you can snap a photo of the question straight from your prep book and upload it; Ryna reads the text and the options via OCR.
Treat the output as a learning aid, not an answer key: keep the official answer key as your source of truth and use Ryna for the 'why'. Especially on interpretation-based questions (reading passages, philosophy), always cross-check against the official key. The free plan solves near-unlimited questions daily; photo upload and Deep Thinking mode for tough questions come with Plus ($12/mo, 399.99 TRY).
Why use Ryna AI for this
Distractor analysis: it explains not just the correct option but why each of the other four is wrong, one by one — that's where the real learning happens.
One tool, every subject: reading comprehension, history, geography, biology, physics, chemistry, math and philosophy questions, all in one place.
Photo upload (Plus): snap a question from a prep book, a photocopied test, or handwriting, and it reads the options via OCR.
Answer-key verification: ask 'the key says D but I got C — which is right and why?' and resolve the contradiction.
Question-type coaching: ask 'what trap does this passage-question type always use?' and it surfaces the recurring distractor pattern.
Post-mock bulk review: paste all your wrong answers, and it groups them by topic and tells you which subject to study next.

How it works — step by step
- 1
Enter the question with its options
Go to chat.rynaai.com. Paste the stem AND all five options (A-E) — not just the question. On the Plus plan you can snap a photo from a prep book; handwriting and photocopies work too.
- 2
Turn on Deep Thinking for hard questions
For long passages, multi-step physics/chemistry problems, or options that are very close, switch on Deep Thinking mode in the chat (Plus). It reasons for 30-60 seconds; skip it for easy questions.
- 3
Read the reasoning, not just the letter
Ryna explains why that option is right and the others are wrong, not just the letter. You can ask 'why C and not A?' one by one — that's where the learning happens.
Example: input → output
You ask
Solve this TYT biology question and explain every option. Which of the following does NOT increase the rate of photosynthesis in a plant? A) Increasing light intensity (up to a limit) B) Increasing the CO2 in the environment C) Dropping the temperature from 35°C to 5°C D) Increasing leaf chlorophyll content E) Adequate water uptake by the roots
Ryna AI returns
Correct answer: C The question asks what does NOT increase the rate, so we're looking for the option that lowers it or has no effect. Photosynthesis is an enzyme-driven reaction; enzymes work fastest at a specific optimum temperature. Option by option: • A) True fact but doesn't answer the question: light powers the light-dependent stage; up to a limit, more light INCREASES the rate. Eliminated. • B) CO2 is the raw material of the Calvin cycle; more of it INCREASES the rate. Eliminated. • C) CORRECT ANSWER: dropping below the optimum, to 5°C, slows enzyme activity and LOWERS the rate — i.e. it does not increase it. This is the one asked for. • D) Chlorophyll is the light-absorbing pigment; more of it INCREASES the rate. Eliminated. • E) Water is the electron/H source in the light-dependent stage; adequate water supports the rate, doesn't lower it. Eliminated. The trap: most students read the question as 'increase' and mark A or B. The keyword is the capitalized 'NOT' — don't miss the negative stem. Reinforcement: if you'd like, I can give you 2 similar questions on 'enzyme-temperature relationships' to solve yourself.
Pro tips
- Always paste the options — if you give only the stem, Ryna can't see the distractors and you lose the most instructive part. Five options = five explanations.
- Ask 'why not A?' option by option. Point out the option you most often fall for and have it explain separately why that one is tempting but wrong.
- On reading and interpretation questions two options can look reasonable; tell Ryna to 'stay between these two and argue for and against each', then compare with the official key.
- On quantitative subjects, ask 'which student mistake is each distractor designed for?' — it names unit, sign, and rounding traps so you start spotting them in the exam.
- After a mock, don't go one by one — paste 15-20 wrong answers at once and say 'group by topic and prioritize what to review'. You get a clean review list instead of mental clutter.
- When uploading a photo (Plus), hold the paper flat, light it from the front, and make sure all options are in frame — a half-read option throws off the whole solution.
Common mistakes to avoid
- ✕Pasting only the stem and skipping the options — Ryna will guess the right one but can't run the distractor analysis, so you miss the core of the learning.
- ✕Taking only the correct letter and skipping the reasoning. The same question type shows up again in the next mock; skip the 'why' and you leave the points on the table again.
- ✕Treating Ryna's answer as the official key on interpretation/reading questions — here AI picks the most plausible option but may not match the official key; always cross-check.
- ✕Photographing the mock crooked or in poor light — OCR misreads an option and the whole solution is built on the wrong choice.
- ✕Thinking test-solving is a shortcut to finish homework. Copy it and you'll freeze in the exam; understand first, then solve 3 similar questions yourself.

FAQ
Which subjects' test questions can it solve?
Turkish (reading, grammar), math, geometry, physics, chemistry, biology, history, geography, philosophy and English — most multiple-choice questions in TYT/AYT and school curricula. It's strongest on quantitative and knowledge-based questions.
Can Ryna pick the wrong option — should I trust the answer key or Ryna?
Always keep the official answer key as your source of truth. On clear, quantitative, knowledge-based questions Ryna is very reliable; but on interpretation-heavy questions (especially reading passages, philosophy) it picks the most plausible option and can occasionally diverge from the official key. Use Ryna for the 'why', not the 'letter' — when they conflict, have Ryna explain the difference.
Can it solve a test question from a photo?
Yes, on the Plus plan. Upload a prep book, photocopied test, or handwritten question; Ryna transcribes the question and options via OCR, then solves it. For best results hold the paper flat, light it from the front, and keep all options in frame.
Does it also explain why the other options are wrong?
Yes, and this is its most valuable feature. When you give it the options, it addresses each distractor individually: 'B gives a detail, not the main idea', 'D is designed for a student who makes a unit error'. You can also say 'I keep falling for A, explain that one specifically'.
Is having it solve tests cheating — what would my teacher say?
If you just copy the answer, it's close to cheating and won't help you in the exam. The right use: read the distractor explanation, learn the question type, then solve similar questions yourself. It's a tool for understanding the topic; teachers can tell the difference between a memorized answer and genuine study.
