How many practice questions per day?
During onboarding you set minutes per day (30, 45, 60, or 90) and your organic chemistry final date. That choice sets how many organic chemistry practice questions appear in today's drill.
| Daily study time (onboarding) | Questions per day |
|---|---|
| 30 min | 4 |
| 45 min | 5 |
| 60 or 90 min | 6 |
Questions are fixed for the day — leave and return without losing progress. Missed reactions reappear tomorrow until product and mechanism order are both correct.
Each question: two parts (mechanism practice exam style)
Part 1
What is the major product?
Each question shows reactants, reagents, and conditions. Choose the major product from up to four structures — wrong answers include real minor products and classic exam traps.
Part 2
Put the curved-arrow steps in order
Mechanism steps appear shuffled. Tap them in the order they happen. Single-step reactions skip this part. You need both Part 1 and Part 2 correct for mastery.
After you check answers, the reveal names the trap if you picked a classic wrong product, shows the correct major product, and lists the full mechanism sequence. That feedback is what makes spaced repetition orgo practice stick.
Exam traps in the Daily Drill (with free study hubs)
Wrong choices are not random. They mirror the distractors your professor and the MCAT use — study the hub, then drill the pattern in the app.
| Trap pair | What exams test | Free guide |
|---|---|---|
| SN1 vs SN2 | Same substrate and solvent, different stereochemistry (inversion vs racemization) or different rate when you change nucleophile strength. | SN1 mechanism vs SN2 |
| Zaitsev vs Hofmann elimination | Bulky base (t-BuOK) favors the less substituted alkene; small base often gives Zaitsev (more substituted). | E1 vs E2 & Zaitsev/Hofmann |
| Markovnikov vs anti-Markovnikov addition | HBr alone vs HBr + peroxides (ROOR) on an alkene — regiochemistry flips with radical conditions. | Alkene addition & Markovnikov |
| Hydroboration vs oxymercuration | Both give Markovnikov alcohol placement from an alkene, but hydroboration is syn stereochemistry; oxymercuration avoids carbocation rearrangement. | Alkene addition stereochemistry |
| Lindlar (cis) vs dissolving metal (trans) | Partial reduction of an alkyne to an alkene: Lindlar gives cis; Na/NH₃ (dissolving metal) gives trans. | Oxidation & reduction (Lindlar vs dissolving metal) |
| Br₂ addition vs NBS allylic bromination | Br₂ adds across a π bond (anti); NBS at allylic positions under radical conditions — different reagent, different family. | Substitution & NBS (allylic) |
| Grignard vs acidic proton | RMgBr adds to carbonyls in dry ether; alcohols and water quench the reagent before C–C bond formation. | Grignard mechanism |
| Wrong R/S after substitution | SN2 inversion at a stereocenter — the major product is not retention. | Stereochemistry (R/S, meso) |
Score by reaction family
The Study tab tracks mastery for each family in the 56-reaction library. Home may call out your weakest area — for example, "You still miss elimination" — so you know what to read before the next drill.

A few minutes a day beats cramming the night before
Set your final exam date in OrgoMech, run today's drill, and let missed reactions come back until you own both product and arrows.
Daily Drill FAQ
Spaced repetition organic chemistry practice in OrgoMech.
- What is the OrgoMech Daily Drill?
- A fixed set of exam-style organic chemistry questions each day. Part 1 is major product multiple choice; Part 2 is ordering mechanism steps. Both must be correct for the reaction to count as mastered.
- How many organic chemistry practice questions do I get per day?
- It depends on the daily study time you chose in onboarding: 30 minutes → 4 questions; 45 minutes → 5; 60 or 90 minutes → 6. Today's set stays the same if you leave and return.
- How does spaced repetition work in the Daily Drill?
- Any reaction you miss on product or mechanism order comes back at the start of tomorrow's drill until you get both parts right. Other slots favor families you're weakest in.
- Are wrong answers random in the drill?
- No. Distractors include the real minor product and named traps such as SN1 vs SN2, Zaitsev vs Hofmann, and Markovnikov vs anti-Markovnikov — the same mix-ups exams use.
- How is Daily Drill different from the reaction predictor?
- Predict lets you draw any reactant and pick reagents. Daily Drill is structured quiz practice with scored mastery by reaction family — better for a short daily habit before your final.
- Does the Daily Drill use my final exam date?
- Yes. Onboarding sets your orgo final date and daily minutes; Home shows the countdown and Study highlights families you still miss.
- Is the Daily Drill on the web?
- This page explains the study loop. The drill itself runs inside OrgoMech Pro on iPhone or iPad.
- Who is daily orgo practice for?
- U.S. undergraduate students and pre-meds who want a few minutes of product + mechanism practice each day before midterms, finals, or MCAT organic chemistry review.
