Yes - the bank is maintained against the current exam outline, and questions are revised when the exam changes.
No honest practice platform can guarantee a pass. What realistic practice does is show you - before exam day - exactly which domains are weak, and give you the repetitions to fix them. That's the difference between hoping you're ready and knowing where you stand.

For most countries, the price you see is exactly what you pay - tax is already included. Where local law requires it to be added separately, it's shown clearly at checkout before you pay, so there are never any surprise fees.
Access is instant after payment and runs for your plan's full window from that moment. When the window ends, your local progress stays on your device - you can buy another window any time and pick up where you left off.
Yes - the whole platform is mobile-first: practice, mistake review, and analytics all work on any phone, tablet, or laptop with a browser. Nothing to install.
Every answer feeds your per-domain accuracy, readiness score, and weak-area list. Instead of re-reading everything, you drill the domains that are actually costing you points - that's what moves a score in days, not months.

Real feedback from I40TA candidates on Reddit.
"almost skipped studying for the codesys part since i thought id wing it. glad i didnt, the practice questions on that topic saved me. passed first try, still kinda surprised tbh."
"i was behind on studying for weeks, kept putting off the robotics safety and machine guarding stuff cause it felt boring. ended up going thru i40taexam.com the last two weekends before the exam and it actually stuck. passed, no drama."
"honestly wasnt sure id pass this one. the compressed air cost calculation questions kept tripping me up in practice but after a few rounds of mistake review it finally clicked. walked into the exam calmer than expected and got through it fine."
