How long is YKS prep on YouTube? 15 courses timed

The AYT courses for a sayısal score take 244 to 334 hours to watch on YouTube. We measured the fifteen TYT and AYT courses on our YKS list on 29 October 2026, counting every video to the last: one course each for AYT matematik, fizik, kimya, biyoloji and geometri comes to 244 hours with the lightest choices and 334 with the heaviest. The fifteen together are 785 hours over 1,866 videos.

With TYT Türkçe, fizik and kimya added, the lighter route is 359 hours, 239 at 1.5×: about an hour a day at 1.5× from now until June. And the kamp names are not a promise of an hour a day: Mert Hoca's 90 Günde AYT Matematik is 119 hours, 79 minutes a day for its 90 days, while Celal Hoca's 55 Günde AYT Kimya needs 41.

Every course, measured

Ranked by total. "1.5×" is the total watched at one and a half times speed, and "Avg" the average video.

Course	Videos	Total	1.5×	Avg
AYT Mat, Mert	183	119 h	79 h	39m
Tarih, Retro	166	102 h	68 h	37m
AYT Kim, Ferrum	166	81 h	54 h	29m
AYT Mat, Eyüp	273	77 h	51 h	17m
AYT Fiz, Özcan	177	75 h	50 h	26m
TYT Fiz, Özcan	119	55 h	37 h	28m
AYT Kim, Görkem	71	46 h	30 h	39m
TYT Tarih, Aycan	140	39 h	26 h	17m
AYT Kim, Celal	69	37 h	25 h	33m
TYT Kim, Ferrum	93	36 h	24 h	23m
AYT Bio, Dr. Bio	101	30 h	20 h	18m
Geometri, Eren	109	28 h	19 h	15m
AYT Bio, Aras	98	27 h	18 h	16m
Türkçe, Aker	71	23 h	15 h	20m
Edebiyat, Aker	30	10 h	7 h	20m

Totals are rounded to the hour. Mert is Mert Hoca, Retro is Mehmet Celal Özyıldız on Retro Yayıncılık, Eyüp is Eyüp Boncuk and Eren is Eren Kesim on 3D Yayınları, Özcan is Özcan Aykın, Görkem is Görkem Şahin on Benim Hocam, Aycan is Aycan Söylemez and Aras is Aras Tuğcu on 3D, Celal is Celal Hoca, Dr. Bio is Dr. Biyoloji, and Aker is Aker Kartal on Retro. None of the fifteen has a private or deleted video. Each course name opens its live page, where the total is current and you can tick off what you have watched. The same courses are on our list of free YKS courses, with what each covers.

The kamp courses: minutes a day for the days they promise

Six of the courses are camps named for the days they take. Divided out, the minutes of video a day they need:

Camp	Days	Video	A day	At 1.5×
90 Günde AYT Mat	90	119 h	1 h 19 m	53 m
46 Günde AYT Kimya	46	64 h	1 h 23 m	56 m
TYT Kimya, Ferrum	22	29 h	1 h 20 m	53 m
55 Günde TYT Fizik	55	55 h	1 h 0 m	40 m
88 Günde AYT Fizik	88	75 h	51 m	34 m
55 Günde AYT Kimya	55	37 h	41 m	27 m

Özcan Aykın's two physics camps and Celal Hoca's chemistry camp keep to about an hour a day or less, so their names hold. Mert Hoca's maths camp and both of Ferrum's chemistry camps need closer to an hour and twenty minutes, before the questions you solve yourself. Ferrum's two playlists also hold a revision camp each, Tekrar Soru Kampı: 11 videos and 17 hours in the AYT playlist, 5 videos and 7 hours in the TYT one, which is why their totals in the first table are longer than the camps.

Two routes, and what the list doesn't cover

One course per AYT subject for a sayısal score, with geometri:

Route	Total	1.5×
Lightest: Eyüp, Özcan, Celal, Aras, Eren	244 h	163 h
Heaviest: Mert, Özcan, Ferrum, Dr. Bio, Eren	334 h	222 h
TYT Türkçe, fizik, kimya	114 h	76 h
Eşit ağırlık AYT: Eyüp, Aker, Retro, Eren	216 h	144 h

The choice that moves the total most is the maths course: Mert Hoca's 119 hours against Eyüp Boncuk's 77. Chemistry is next, Ferrum's 81 against Celal Hoca's 37. For eşit ağırlık, Mehmet Celal Özyıldız's history series is most of the route at 102 hours, because it covers TYT and AYT history in one.

Our list has no TYT matematik course yet, and no coğrafya, felsefe or din kültürü, so add those subjects' hours on top of these routes.

Hours a day until June

The lecture time a day for the lighter sayısal route with TYT Türkçe, fizik and kimya, 359 hours, watching every day:

Time left	1×	1.5×	2×
12 months	58 m	39 m	29 m
9 months	1 h 18 m	52 m	39 m
8 months	1 h 28 m	58 m	44 m
6 months	1 h 57 m	1 h 18 m	58 m
4 months	2 h 56 m	1 h 57 m	1 h 28 m
3 months	3 h 55 m	2 h 37 m	1 h 57 m

From the end of October, June is about eight months away: an hour a day at 1.5×. The heavier route, 448 hours, is a quarter more at every row. YKS is decided by the questions you solve and the denemeler you sit, so treat these as the floor and plan your practice on top. Maths at 2× is hard to follow; what each speed costs →.

Check the total covers every video

Some playlist length tools add up only the first 100 videos and stop without saying so. Nine of these fifteen playlists are longer than that, and on them the first 100 videos come to 366 hours of the real 606. Eyüp Boncuk's AYT Matematik loses the most: its first 100 videos are 25 hours of 77. Mert Hoca's camp shows 69 of 119, the Retro history series 60 of 102, and Özcan Aykın's AYT physics 46 of 75. If a total looks short for a playlist of more than 100 videos, here is how to check it.

Video counts mislead the other way too. 110 of Eyüp Boncuk's 273 videos are Shorts, an hour and a half together; his 163 lessons are 75 hours. Eren Kesim's geometri has 51 lessons among its 109 videos, and Aras Tuğcu's biology 67 among 98. Judge a course by its hours, not its video count.

Plan the one you choose

Paste a course's link on the home page, or click its name in the first table, and set your speed and daily minutes in the planner: it gives you a finish date and the videos for each day, and you can put the sessions in your calendar. Tick each video as you finish it and the time left updates; the course stays in your list on the home page, to pick up where you stopped. The exam date guide works back from the exam day, the KPSS guide measures the other big Turkish exam, and how long a free YouTube course is puts YKS next to 23 other subjects.

118 hours 58 minutes over 183 videos, measured on 29 October 2026: 79 minutes a day for its 90 days, 53 at 1.5×. It is the longest course on our YKS list.

Is 55 Günde AYT Kimya really 55 days?

Yes, at under an hour a day. Celal Hoca's camp is 37 hours 29 minutes over 69 videos, 41 minutes of video a day for 55 days, or 27 at 1.5×. It is the lightest of the three AYT chemistry courses on our list.

How long is Eyüp Boncuk's AYT Matematik?

76 hours 46 minutes over 273 videos, measured on 29 October 2026. 163 of them are lessons, 75 hours 11 minutes; the other 110 are Shorts. At 1.5× it is 51 hours.

Why might a total differ from the playlist today?

These totals were measured on 29 October 2026. Most of these are 2027 series still being recorded, so they grow, and videos can go private. Each course's page here, and the YKS list, shows the total as it is now.
