Highly efficient and student friendly

Zainab ma’am is more of your college senior who helps you throughout your college, she’s not just a faculty but a mentor. The tech team is very helpful, you bring any issue to them and they try to solve that very fast.
The content of the app, the feature to create multiple bookmark lists, it’s all just so helpful.

Brilliant stuff and brilliant team behind this project!

The app crashes and just stops whilst playing videos; very poor explanations for pyq; qbanks

The app crashes and just stops whilst playing videos- one has to refresh repeatedly; which is a huge lapse- also not allowing two screens to be used simultaneously- hinders students from seamlessly watching videos and solving questions; the explanations for questions are subpar; there should be more information added; so it’s a comprehensive learning device. There should be an option to restart a qbank from where you left off without your progress getting erased if you start other qbanks midway simultaneously. The grand /mini tests should have option to move to the next set of questions without forcibly having to do it over a long period because everyone has their own pace and strategy & it causes a waste of time.

Please Fix the Screenshot Blocking Issue

The content is great, but the screenshot detection policy is too aggressive. My account has been blocked multiple times simply because I took screenshots for personal study purposes while using Split View on my iPad. Sometimes BTR wasn’t even the active window.

Other coaching apps block the content, not the entire account. Repeated account suspensions disrupt studying and require contacting support every time.

Please address this in a future update so students can study without unnecessary interruptions.

Fantastic Learning App with a Few Streaming Issues

I’ve been using COREBTR for some time now, and overall it’s a really good app for exam preparation. The interface is clean, easy to navigate, and the content is well organized. Finding lectures, notes, and tests is straightforward, and the app generally performs well.

The feature I love the most is the test interface. It feels very similar to the actual exam environment. The option to take mini tests also on web portal is especially useful because it gives u a real exam-like experience using the web portal on PC or ipad.

A few things that could be improved:

• Video playback sometimes has glitches and occasional stutters.
• The video quality automatically drops despite having a stable high-speed internet connection.
• Even after manually selecting a higher resolution, the app sometimes switches to a lower quality on its own.
• The streaming algorithm seems a bit aggressive in reducing quality, which can be frustrating during lectures.

Other than these issues, the app offers a solid learning experience and has become one of my regular study tools. If the video playback and quality selection issues are fixed, it would easily deserve a higher rating.

Awesome😍 but need one improvement.

Content and user interface of app is top-notch. I never feel cheated, disappointed from corebtr at the price i got the course.
One scope of improvement is required in “one device policy”, if by chance you lost your phone/ipad or want to buy new device then this policy doesn’t allow you to do so, there should be SOME T&C to “one device policy” for people who are genuinely need to switch to another device.

Great resource

The bugs in the app are gradually being fixed, great that coreBTR team is taking inputs from students😍, the tech team are also quick enough to resolve any issues with login…I know it would not be easy for u mam but it would be great for us if we can take screenshot of just the qsn +/- explanation to add it in our notes😅

Nice app

Good features that stands out from the market of other Education apps for neat PG preparations changes in the way of login, the way of solving questions, the way of bookmarking everything has changed from old pattern to a new pattern, which is more helpful. Explanations of the QBank are more clear.

Very very disappointing… Need much more improvement, too much low volume in some videos

• The audio in video lectures is very low, which is extremely frustrating. I have to turn off the fan and AC just to hear properly.
• There is no response from the support team on WhatsApp.
• The app lacks a good interface, whereas the Marrow app is much smoother.
• Background updates are not available, unlike in the Marrow app.
• You cannot download more than 10 videos, which means you need Wi-Fi again and again.

Voice volume problem

App is very good. There is some problem with voice when earphones are connected, volume becomes very low when i try to listen the videos while putting them on. Otherwise it’s okay to listen them normally.

Some major issues still remain unfixed

1) Video gets paused when I slide down my iPad menu bar to change volume or brightness, and it doesn’t automatically plays back..it remains paused + it changes from full screen to a smaller window
2) Earphones: the video pauses with my earphones but it doesn’t play back, it’s not an issue for me with other apps and I’ve heard other users using different earbuds brands complain abt the same
3) Homepage again n again- if I go to another app while using coreBTR the screen remains in position for like 5 mins, if I take longer than that it redirects to the Homepage!
It’s a major issue if someone is writing online notes along the vid, or if we want to look something up on the Internet
4) Auto Resolution- with the new update I’m unable to change the quality of the video, I can’t watch the video on Auto all the time, the quality gets poor
5) A request to bring HIDE ANSWER/SHOW ANSWER for test reviews, so that we can attempt the ques we skipped and see if we can guess the right ans while reviewing the test only (it’s a difficult job to look for the ques again from the library and then guess the ans, also then what’s the point if I have already seen the correct ans marked out in the review of test)
6) Guessed Qs - there’s an option to mark Qs that I’ve guessed while doing the test but there’s no way knowing which ones I marked as Guessed AFTER I finish my test, if u could pls tag in those Qs too, that would be of great help to know if we did guess smth correctly.
Overall a great app but that would be amazing if the tech team could fix these issues thanks!

Lack of support and broken promises from CoreBTR

As a Cerebellum Mission subscriber, I was clearly informed that I would have free access to the Core BTR app until January 19th, without any additional charges. However, I’m currently unable to access the app as promised.
What’s more frustrating is the complete lack of response from the support team. My messages have gone unanswered, and calls are not being attended. For a platform that actively promotes new subscriptions, ignoring existing users raises serious concerns about customer care.
I’m not asking for anything beyond what was promised. I simply expect transparent communication and timely support. I hope the team addresses this issue soon and improves how they treat their existing users.

This App Fixes What Marrow Couldn’t.

The Marrow QBank UI is excellent. However, I feel it lacks better customization options for bookmarks and dedicated PYQ sections for each subject. Overall, it seems like Dr. Zainab Ma’am has incorporated most user feedback and created something that many platforms were previously missing in their QBank and custom modules

Best app for neet pg or inicet preparation

Dr. Zainab ma’am is truly a magician, the way she makes all the concepts so easy and concise is extraordinary. The app works beautifully and seamlessly and I love how the questions have different bookmarks that make it easy to sort the important questions. The matter is more elaborate than the previous versions and it reduces the need to check other material.

It’s not an app, it’s an ecosystem

Initially every app has ups and downs especially the ones with a targeted audience of 100k+ students at a time, but the content, the clarity and most importantly the intent behind this app puts it head and shoulders above the rest. Dr. Zainab is a godsend, and even if I’ve never met her, I’ll always be her student. Here’s to all days, from MER to coreBTR.
Much gratitude ma’am!

Built by a Student Mind, The Qbank That Actually works for Student

Everyone was already a fan of BTR, but CodeBTR just proves why it stands out even more.

The elimination feature is incredibly smart,it actually trains your brain to think the way you should in exams. You don’t just attempt questions, you strategically solve them.

And the bookmark system? Absolute genius. Like actual effort was pu into it
You don’t just bookmark randomly,you categorize your learning:
New Information,Revisit Later, My Choti Copy, Recall Error woowwww✨

As Zainab ma’am always says she thinks like students… and CodeBTR is the perfect proof of that❣️

app experience can be significantly improved

the app doesn’t properly support earphones, the content can be paused through earphones but can’t play again. it’s not a glitch in my earphones i checked w other apps and disconnected and reconnected them as well.
the rewind and fast forward features should not just be restricted to the small circles in which they appear on screen since it makes it very touch to go back multiple sets of 10s at once and you’ve to press once and wait and then do the same again.
the app also crashes in the middle of the video sometimes although it isn’t so frequent w me it is an area which can be looked into.
the content has been significantly increased in length and depth which is ideal since the doubt of if its enough it vanquished however the integration of things has still been less than ideal as this could’ve been a great time to bring everything related to a topic in one place rather than studying path features in one video, radiological appearance in one and the treatment aspect in another (ESPECIALLY REFERENING BONE TUMOURS)

Best app best support survives

I am a Cerebellum subscriber and have been using the Cerebellum app for the past 3 years. I lost my registered phone number, so I was unable to log in to CoreBTR and faced many issues.
Since CoreBTR is a new app, I had little hope of receiving the OTP on my email like in Cerebellum. However, within 24 hours, the support team contacted me and helped me manually log in to my CoreBTR account.
I am very happy with their support. Thank you so much, Zainab ma’am, Ravi sir, and the entire support team.
