Moodle VS plexus

One example is: https://moodle.org/

It's probably copyright violation to copy their exercise sets (depends on the license and where they got them). There are existing maths quiz grading systems that could be used for similar purposes (based on your description; I haven't done that Udacity course), and I'd recommend STACK [1], a Moodle [2] plugin. Both are open source.

[2] https://moodle.org/

do yourself a favor and look at the code: https://github.com/moodle/moodle/blob/master/notes/index.php (I will go and search which plugins are not checking for the "course-login" now...)

Why do not use proper LMS like Moodle https://moodle.org/?

What are the differences between moodle.net and moodle app?

I'm working on this with a friend since yesterday. We've reinstalled several different versions of moodle from moodle.org with different PHP Versions, having this as our best outcome.. We get the proper Moodle look just before Installation, after installing it looks like this

REDCap is not really the best tool for this. I would suggest something like Moodle: https://moodle.org/

Probably too "full blown" but Moodle is decent: https://moodle.org/

I use >10 apps from >5 different finance-related entities. All of them work as intended on CalyxOS. Yet YMMV. You may want to run the ones you're intending to use through Plexus.

If you cannot afford a Pixel in your region and still want a degoogled ROM I would suggest you DivestOS (it is based on LineageOS but degoogled) if you don't need microG or Sandboxed Play Services. See app support on Plexus. Maybe you will find a phone that is reported as Tested and Working + Lockable bottloader.

i understand, however what i mean is, you dont need google, the apps work just fine, also sandboxed gapps is worse than microg, not all apps are gonna work still, some wont, microg probably got more compatibility. both cant support in app purchases, however any non gapps supported purchases will work just fine, specially if its in the browser, as well as banking apps work, its rare if a banking app wont work, however you may find apps that dont work. btw i think that you confused with sandboxed gapps and normal gapps, to be clear as i said, sandboxed gapps will not be the same as normal gapps provided within the system without sandboxing, the one graphene did was sandboxing it and this not only is less compatible than microg but you wont get any benefits like in ap purchases, etc, so either microg or a normal phone w gapps if you require apps that only work with it. i can test whatever apps you wanna use to make sure they work. or there is also this site https://plexus.techlore.tech/ to check which work or not or which work on graphene and not calyx, vice versa.

You might like the Plexus tool to help you figure out which apps may or may not work on these "de-Googled" Android ROMs. However, I do not know how current is the information. I use CalyxOS, and I have found a lot of apps work for me.

Check if your apps will work properly if you don't install an optional GApps package with this crowdsourced project: https://plexus.techlore.tech/

I think this tool will help you.

As far as app compatibility is concerned on a custom ROM, you can check out Techlore's [Plexus](https://plexus.techlore.tech) project (I don't know if that list has been updated in a while or not so try an app and see if it works for you). I have heard positive experiences from other users that PayPal and CashApp work just fine on CalyxOS.

You can check if your apps will work well with Microg or without any Google services here.

Look at Plexus for app compatibility.
