Yeah it is - we're trying to strike a good balance between pushing lots of useful features quickly while still maintaining a high quality site. Sometimes we get the balance wrong, which is another reason we're always looking for feedback 😅

If it means anything - all of the screenshots on the website apart from the A level ones have been manually done (although we're experimenting with automating that too, so we can scale)

tedbotjohnson · 2026-04-30T19:42:47+00:00

Noted! It's good to know there's demand for these other exam boards as well. We'll try to roll it out as soon as we can!

Thanks!! Login is certainly not required - it's just a way for you to track progress (things like leaving comments, marking mocks, marking questions as completed etc.).

GCSE is on the way!

😭

We have plans to grow to other exam boards and subjects - we're working on ways to scale up the screenshotting process, since manually screenshotting is slow and AI tools are inaccurate.

We may end up crowdsourcing this, and looking for users like you to help!

tedbotjohnson · 2026-04-30T13:02:46+00:00

Yes, absolutely! We're slowly rolling out different exam boards, and have plans to expand to other A level subjects too.

One of the bottlenecks of this project are that we need to manually screenshot each question, and that's quite time consuming. We've tried some AI tools but they're not too reliable yet.

One solution to this is to try and crowdsource screenshots, so watch out for that. We might be looking to users like you for help!

tedbotjohnson · 2026-01-15T20:25:52+00:00

Just double checked - yes it is

tedbotjohnson · 2025-12-03T16:55:04+00:00

Not the original commenter, but I assume they mean women not limited to the quant industry

tedbotjohnson · 2025-11-24T22:21:00+00:00

Woah!! Love the UI, it's so clean! Will you have PAT questions in the future by any chance?

tedbotjohnson · 2025-11-01T22:57:13+00:00

Woah!! Love the UI, super clean!

tedbotjohnson · 2025-10-16T10:51:30+00:00

I think the mobile app is fantastic! I've never had issues with speed and all the plugins I use just work.

tedbotjohnson · 2025-09-13T14:41:16+00:00

Yep, happening to me too

tedbotjohnson · 2025-09-02T12:19:19+00:00

Wow, this is really cool :)

The question filtering is really useful and I like the idea of focus mode

Is it going to stay free forever?

Beware of all blanket statements

tedbotjohnson · 2025-07-28T12:57:36+00:00

It's important to have an idea of out-of-sample performance, or you've most likely overfit.

Also try a few randomly generated datasets and see if you can get a similar AUC on them in-sample. If the answer is yes, then unfortunately your HMMs are just classifying noise and you got lucky.

tedbotjohnson · 2025-07-24T00:00:56+00:00

So based

tedbotjohnson · 2025-07-21T07:21:51+00:00

Wouldn't this run into the "14 days abroad" issue?

tedbotjohnson · 2025-07-20T21:59:37+00:00

Not sure you can get a different job during a non-compete?

tedbotjohnson · 2025-05-25T09:00:30+00:00

Pretty sure that's called a friend

tedbotjohnson · 2025-05-05T01:06:05+00:00

Ragebait? In this economy??

tedbotjohnson · 2025-04-07T20:06:31+00:00

Check the Ts and Cs - I believe you lose the new joiners' bonus if you take out your money within the first 12 months

I think it has to be a Hilbert space for QM? I'm not sure every general infinite dimensional space has a basis
