Questions
How often is new practice added?
Every Monday at 9:00 am (India time): 3 new Lab Challenges from easy to hard, a Debug Case with a real bug to find and fix, and 10 new questions in the AI Mock Interviewer. Members get a short email when it is live, and can turn that email off.
How does billing work?
Pro is a monthly subscription through Razorpay (UPI Autopay, cards and more). It renews every month until you cancel.
Can I try Pro before paying?
Yes. Sign in (it is free) and you can solve two Lab Challenges with the hidden testbench, and do a 2-question AI mock interview with a scorecard, without paying anything.
What is the founding price?
Until 31 October, the first 20 members pay ₹199 a month for their first 3 months instead of ₹299. From the fourth month it renews at ₹299 on the same UPI mandate, so there is nothing to do. The founding price is for UPI AutoPay (Razorpay's offer covers one payment method); paying by card, Pro is ₹299 a month. It is once per person, and it stays yours: if you cancel and come back before your 3 founding months are used, you resume at ₹199.
Is there a plan without autopay?
Yes: the 30-day pass. You pay ₹299 once with UPI, card, netbanking or a wallet, and get all of Pro for 30 days. Nothing renews and no mandate is set up. Buy another any time to add 30 more days, or switch to the monthly plan from the Pro page.
Can I cancel?
Yes, any time, from your account page in one click. You are not charged again, and you keep Pro until the end of the month you have paid for.
Do you give refunds?
No. Like a streaming subscription, you pay for a month at a time: if you cancel, you keep Pro for the rest of the month you paid for, and that payment is not refunded. If you were charged twice or by mistake, email hello@siliconpath.in and we will put it right.
Do I need to install anything?
No. The VLSI Lab runs Verilog simulation and synthesis inside your browser, so it works on any laptop. The first run downloads the tools, then they are cached.
What about courses I already bought?
They are yours for life, whatever happens to Pro. Pro adds new members-only tools; it does not replace anything.
