![]() The PSI Insurance Test Prep app is powered by Memorang, an advanced AI learning platform developed by MIT engineers and physicians to make advanced learning simpler for any subject. Additional study-packs and practice tests for all your insurance exams are available for purchase. ![]() Leaderboards to see where you stand and make studying fun.Detailed score report with analysis of your performance in each topic.210 questions similar to what you’ll see on test day.Once purchased, you will receive a second email containing your access code. PSI premium practice tests are purchasable through the Online Store and fulfilled in the Memorang platform. Testing Mode adds a timer and no hints, just like the real test. Designed to simulate your test-day experience, our premium practice tests mirror the national test's objectives and feature sample questions similar to those you'll see on the actual test. If you combine that information with screen size and device information you have everything you need to identify issues in near real time.Build your confidence and prepare for test day with PSI practice tests. This answer I gave has all the relevant metrics you may want to gather and monitor for site performance. One way to check is to actually monitor this information on your site. When we teach Tolerance Analysis in our Tolerance Analysis Courses, we teach it from the point-of-view of careful application of dimensions. Our Tolerance Stackup and Tolerance Analysis methods very powerful and they are easy-to-learn and easy-to-use. It has no affect on your score on PSI as that is calculated each time from "lab data".įield data is there for diagnostics (as RUM are far more reliable and help identify errors automated testing may miss such as an overloaded server, problems at certain screen sizes etc.) I have websites that load in under 2 seconds but they fail the PSI tests.Īre you sure? It may show 2 seconds on automated tests (for desktop) but in the real world how can you know that? We teach our Tolerance Analysis training courses regularly around the US and around the world. Using Lighthouse, GTmetrix generates scores for your pages and offers actionable recommendations on how to optimize them. It is collected from real visitors to your site. GTmetrix is a free tool to test and monitor your pages performance. No field data is real world data, also known as RUM (Real User Metrics). This is why I said "similar" scores in the previous paragraph. ![]() Lighthouse changed to version 6 scoring earlier this year, to reflect the items that really matter to the end user. You should find that you get similar scores if you compare the desktop tab of PSI report to them as that is unthrottled.Īnother difference (although I am not 100% sure) is that I think those sites are still using Lighthouse version 5 scoring at their core. This is the main reason you will see vastly different scores as they do not apply any form of throttling to the CPU or network speeds. all check the desktop version of the site. Mobiles have lower processing power and may be used "on the go" without WiFi. ![]() It does both of these to simulate a mid-tier mobile phone on a 4G connection. Page Speed Insights (PSI),uses lighthouse to power it.Īs part of this it uses simulated network throttling to simulate network latency and slower connection speeds (comparable to fast 3G / slow 4G). Is this because it uses a slower connection to the website? I have read that it's a fast 3G connection? The desktop tab of PSI should be similar but yet again uses different metrics for score that the others do not appear to have updated to (at time of writing). You will always score lower on PSI mobile tests as the other sites do not use throttling. Page Speed Insights (PSI) simulates a mid tier mobile phone on slow 4G connection. Late answer but hopefully this will help people understand the difference.
