This is one of the most consequential traps in the language, because getting it wrong does not just sound off — it tells your listener something untrue. English uses two different verbs, "take an exam" and "pass an exam." Russian uses one verb in two aspects: imperfective сдава́ть means to take / sit the exam (the process, with the outcome still open), and perfective сдать means to pass it (the successful result). The aspect alone carries the difference between sitting and succeeding. So the famously bittersweet sentence Сдава́л, но не сдал — "I took it, but I didn't pass" — uses both members of the same pair in one breath. This page makes that contrast automatic.
The core contrast: process vs result
The pair сдава́ть / сдать ("hand in, hand over") behaves like any aspect pair (see the aspect overview). The imperfective names the activity; the perfective names the completed result. With экза́мен that ordinary aspect logic produces an extraordinary meaning split:
- сдава́ть экза́мен (imperfective) → to take / sit an exam — you are doing the exam; nothing is said about whether you succeed.
- сдать экза́мен (perfective) → to pass an exam — you have brought it to a successful close. сдать without a negation means you passed.
The logic is that the perfective marks a result attained. The natural result of "handing over your exam work" is a pass, so the completed event = success. An incomplete or merely-attempted exam stays imperfective.
За́втра я сдаю́ экза́мен по исто́рии.
Tomorrow I'm sitting a history exam. (imperfective сдава́ть → сдаю́; the present-for-future of a scheduled event — outcome unknown)
Я сдал экза́мен!
I passed the exam! (perfective сдать → сдал; success)
Я весь день сдава́л экза́мен — пять часо́в в аудито́рии.
I was taking the exam all day — five hours in the hall. (imperfective сдава́л — extended process, no claim about the result)
The heartbreak sentence: both members at once
Because the two aspects mean two different things, you can — and Russians constantly do — combine them to say "I sat it but failed":
Сдава́л, но не сдал.
I took it, but I didn't pass. (imperfective process сдава́л + perfective negated result не сдал)
This single line is the whole topic in miniature. The imperfective сдава́л reports that you went through the ordeal; the negated perfective не сдал reports that the ordeal did not end in success. They are not redundant — they describe different things (the attempt and the outcome), which is exactly why both are needed.
Она́ три ра́за сдава́ла на права́ и наконе́ц сдала́.
She took the driving test three times and finally passed. (three imperfective attempts сдава́ла, one perfective success сдала́)
Как сдал? — Да не сдал, пересда́ча в пя́тницу.
How did it go? — I didn't pass, the retake's on Friday. (the question itself uses perfective сдал, expecting a result)
The conjugations — and why they trip people up
The two members conjugate on completely different patterns, which is the second half of the trap. сдава́ть follows дава́ть "to give"; сдать follows the highly irregular дать "to give" (one of the handful of athematic verbs — see the irregular verbs set).
| сдава́ть (imperfective, "take/sit") | сдать (perfective, "pass") | |
|---|---|---|
| я | сдаю́ | сдам |
| ты | сдаёшь | сдашь |
| он/она́ | сдаёт | сдаст |
| мы | сдаём | сдади́м |
| вы | сдаёте | сдади́те |
| они́ | сдаю́т | сдаду́т |
| past | сдава́л, сдава́ла, сдава́ло, сдава́ли | сдал, сдала́, сда́ло, сда́ли |
Two things to internalize. First, the present-tense forms сдаю́, сдаёшь are imperfective — they describe an ongoing or scheduled "taking," never a "passing." Second, since сдать is perfective, it has no present tense at all: сдам, сдашь are its future ("I will pass"). So Я сдаю́ = "I'm sitting it / I sit it"; Я сдам = "I will pass it." Note also the stress shift in the past feminine: сдала́ (stressed ending), against neuter сда́ло and plural сда́ли (stressed stem) — a typical pattern for monosyllabic-root pasts.
Е́сли вы́учу всё, обяза́тельно сдам.
If I learn it all, I'll definitely pass. (perfective future сдам — a confident result)
Студе́нты сдаю́т экза́мены в ию́не.
Students sit their exams in June. (imperfective present сдаю́т — the regular process, every year)
How to say "fail"
There is no single perfective "to fail" that mirrors сдать. You express failure in two main ways:
- не сдать — the plain negation of the perfective: не сдал = "didn't pass / failed."
- провали́ть(ся) (informal) — "to flunk." Both провали́ть экза́мен ("flunk the exam") and провали́ться на экза́мене ("fail at the exam") are common in speech.
Он провали́л экза́мен и расстро́ился.
He flunked the exam and got upset. (informal провали́ть — to fail)
Я провали́лась на собесе́довании.
I bombed the interview. (informal провали́ться — to fail, of a person)
The other meanings of сдава́ть / сдать
The same pair carries two more everyday senses you will meet constantly, both flowing from the literal "hand over":
- сдава́ть / сдать кварти́ру (дом, ко́мнату) — to rent out (as the landlord, who hands the place over to a tenant). The tenant's side, "to rent (from someone)," is снима́ть / снять.
- сда́ча — the noun for change (the money handed back after you pay), and also "surrender." Дать сда́чи colloquially even means "to hit back."
Они́ сдаю́т кварти́ру студе́нтам.
They rent out a flat to students. (сдава́ть — the landlord 'hands over'; the tenant would say снима́ют)
Возьми́те сда́чу.
Take your change. (the noun сда́ча — money handed back)
A near neighbor: поступа́ть / поступи́ть
Russian splits "applying" and "getting in" the same way, with поступа́ть / поступи́ть ("to enter, enroll"). The imperfective is the process of applying; the perfective is the successful admission.
- поступа́ть в университе́т (imperfective) → to be applying to / trying to get into university.
- поступи́ть в университе́т (perfective) → to get in, to be admitted.
So Он поступа́л, но не поступи́л = "He applied but didn't get in" — the exact same process-vs-success shape as сдава́л / не сдал. (For the broader family of study verbs — учи́ть, учи́ться, изуча́ть, занима́ться — see learn, teach, study.)
Она́ поступа́ет в медици́нский в э́том году́.
She's applying to med school this year. (imperfective поступа́ть — the application process is under way)
Брат поступи́л в МГУ на бюдже́т.
My brother got into Moscow State on a state-funded place. (perfective поступи́ть — admitted; the result)
Common Mistakes
❌ Вчера́ я сдал экза́мен пять часо́в. (meaning 'I was sitting it for five hours')
Wrong aspect — for the five-hour process use the imperfective сдава́л; сдал means you passed (a result, not a duration).
✅ Вчера́ я сдава́л экза́мен пять часо́в.
Yesterday I was taking the exam for five hours. (imperfective process)
❌ За́втра я сдам экза́мен. (meaning 'I'm sitting it tomorrow')
Misleading — сдам is the perfective future and claims you WILL pass. For 'I'm sitting it tomorrow' (outcome open), use the imperfective сдаю́.
✅ За́втра я сдаю́ экза́мен.
Tomorrow I'm sitting an exam. (imperfective — scheduled, result unknown)
❌ Я снима́ю кварти́ру студе́нтам. (meaning 'I rent out a flat to students')
Reversed roles — снима́ть is to rent FROM someone (the tenant); the landlord who rents OUT uses сдава́ть.
✅ Я сдаю́ кварти́ру студе́нтам.
I rent out a flat to students. (сдава́ть — the landlord side)
❌ Она́ сдала́ экза́мен три ра́за. (meaning 'took it three times')
Logical clash — сдать is a single successful result; you can't 'pass' something three times. For repeated attempts use the imperfective сдава́ла.
✅ Она́ сдава́ла экза́мен три ра́за.
She took the exam three times. (imperfective — repeated attempts)
❌ Он сдаст экза́мен сейча́с. (meaning 'he's taking it right now')
Wrong tense — сдаст is the perfective FUTURE ('he will pass'); for the action happening now use the imperfective present сдаёт.
✅ Он сейча́с сдаёт экза́мен.
He's taking the exam right now. (imperfective present)
Key Takeaways
- The aspect of сдава́ть / сдать carries the meaning: imperfective сдава́ть = take / sit an exam (process, outcome open); perfective сдать = pass it (successful result).
- Сдава́л, но не сдал — "took it but didn't pass" — uses both members at once: the imperfective attempt plus the negated perfective result.
- They conjugate differently: сдава́ть like дава́ть (сдаю́, сдаёшь — imperfective present); сдать like дать (сдам, сдашь — perfective FUTURE, no present). Past feminine сдала́ shifts stress to the ending.
- "Fail" = не сдать (didn't pass) or informal провали́ть(ся) (flunk).
- Same pair, other senses: сдава́ть кварти́ру = rent out (landlord; tenant says снима́ть); сда́ча = change (money).
- The parallel поступа́ть / поступи́ть splits "apply to" (imperfective) vs "get into" (perfective) university the very same way.

- Verbal Aspect: The Big PictureA2 — Aspect is the spine of the Russian verb: nearly every verb belongs to a pair — imperfective (process, repetition, general fact) and perfective (a single completed whole with a result). This page explains the pair, the consequences for the tense system (perfectives have no present), and why you must decide 'process or result?' before you even pick a tense.
- The Imperfective: Process, Repetition, General FactB1 — The imperfective is the aspect of the action viewed from the inside: in progress, habitual, simply named, attempted, or undone again. This page maps its full range — including the experience reading that often matches English present perfect, and the annulled-result use that has no clean English counterpart.
- The Perfective: Completion, Result, Single EventB1 — The perfective is the aspect of the action viewed from the outside as a single completed whole — finished, with a result that stands. This page maps its uses: completion-with-result, chains of events in narration, single momentary acts, and the simple future. The key insight: result-now means perfective (Я уже́ пое́л).
- Learning and Teaching: Учить, Учиться, Изучать, ПреподаватьB1 — English blurs learn, study, and teach into a handful of verbs; Russian splits them into a cluster governed by case. учи́ть = memorize (+ acc.) OR teach someone something (acc. person + dat. subject); учи́ться = be a student / learn a skill (+ dat. or inf.); изуча́ть = study a subject academically (+ acc.); занима́ться = be engaged in / work on (+ instr.); преподава́ть = teach professionally (+ acc.). Disambiguation tables and the case government that tells them apart.
- The Verb Быть (To Be)A1 — Russian's verb 'to be' is unusual: in the present it is simply omitted (Я студе́нт, Она́ до́ма — no verb at all), with есть surviving only for emphatic existence/possession. The past agrees by gender (был/была́/бы́ло/бы́ли) and the future conjugates normally (бу́ду, бу́дешь, бу́дет…), doubling as the imperfective-future auxiliary. After past/future быть, a predicate noun goes into the instrumental: Он был врачо́м.
- Irregular Present-Tense Verbs (хотеть, бежать, есть, дать)A2 — A small set of high-frequency verbs — хоте́ть (want), бежа́ть (run), есть (eat), дать (give), мочь (be able), печь (bake) — refuse to fit either regular conjugation: some mix endings from both, others keep ancient athematic forms, and all of them must be drilled because there is no rule to derive them from.
