Do I need a maths degree?
No. The core path starts at the beginning, with “What quants actually do”, “Markets from zero” and “The school maths, rebuilt”, written for someone who last did maths at school. The heavier maths the later modules use is built up from there rather than assumed.
Is this useful for interviews?
That is a large part of it. 118 interview questions, 134 puzzles and 28 brainteasers, with worked solutions rather than answers. What it will not do is hand you a list to memorise, because the questions change and the mathematics underneath them does not.
How long does this take?
As long as you give it. There is no completion date and nothing is timed: progress is recorded per item rather than per course, the paths are independent enough to start in the middle, and it is built to sit next to a degree or a job as a reference as much as to be read end to end.
What do I get without paying?
122 of the 720 items, for an email address and nothing else. No card, and no clock running. The subscription opens the remaining 598.
What if I change my mind?
Cancel from the account page and the next renewal stops, with the period you have already paid for left alone to the end. Monthly and quarterly payments are not refunded for a change of mind. An annual payment can be refunded within 14 days, less USD 1.33 for each day you used. After that, cancel and keep access to the end of the year. 122 of the items are open without a card: read those first and decide before any money moves.
What if I already know some of it?
The syllabus is above in full, so you can see exactly what is covered before paying. Inside the app, a three-question roadmap quiz sets where you begin, and everything stays on your journey: the modules before your start remain visible and open, just quieter. The paths are independent enough to start in the middle, and progress is per item rather than per course, so nothing forces you through material you already have.
Can I cancel?
Yes, from the account page, at any time, without writing to anyone. Cancelling stops the next renewal and leaves the access you have already paid for alone, to the end of that period. An annual plan runs to the end of the year you paid for.
Do I need to write code?
Yes, and one of the six paths is about exactly that: Python and vectorisation, C++ where it earns its place, SQL for time series, and profiling. There are 44 notebooks to work through rather than read.
Where do I actually read it?
In the Thuztra Learn app, which holds all 720 items. Part of the library is on this site too: 229 of its 550 web pages read in full in the browser, with no account, and the rest open on a preview. Your progress follows the account rather than the device, so picking it up on a different one costs nothing. Membership is bought on this site, at checkout, and nothing is sold inside the apps: they are for reading and practice.
Is there a certificate?
No. Nobody hiring for this work asks for one, and issuing a certificate would be pretending otherwise. What you get is the material and whatever you can do afterwards.
Do I get an invoice?
Yes. Paying in rupees is a domestic sale and the invoice carries GST; add your GSTIN at checkout and it appears on the invoice. Paying in dollars is booked as a zero-rated export, so no GST is charged.
Is any of this investment advice?
No. It teaches the mathematics, statistics and programming used in quantitative finance. Nothing in it is a recommendation to buy or sell anything, or an offer of any financial product. If you want advice, ask someone registered to give it. The full position is in the terms.
Who do I write to?
team@thuztra.com, which reaches a person.
