![]() ![]() However, they do provide a web-based environment that allows students to navigate through and use the application without requiring the software to be installed. The simulations try to accommodate as much as possible, but due to their nature, they are more limited in scope and are therefore more prescriptive in how students need to accomplish the given tasks. Generally, there are multiple methods for accomplishing tasks in Microsoft Office and Adobe applications. They are designed to simulate the experience of being in the target software, but they are limited in functionality compared to in-app testing. Simulations are replications of the Microsoft Office and Adobe environment that require practical knowledge and skill to complete. All other practice exams are browser based and can be taken at without needing to install anything. ![]() The Microsoft Office Specialist, Adobe Certified Associate, and Autodesk Certified User practice exams all require the GMetrix SMS software (/download) to be installed as well as the target application. Choose from training or testing mode to take your practice test. These tests will be the best option for gauging reading for the certification exam. Designed to simulate your test-day experience, and powered by GMetrixs state-of-the-art exam readiness platform, our Cosmetology Theory practice test mirrors the national tests objectives and features sample questions similar to those youll 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.Practice Exams are based on the certification exams and mimic the testing environment. 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. 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? It is collected from real visitors to your site. 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. ![]()
