If you install the development version of "exams2forms" here from R-Forge, then a basic "obfuscation" of all answers in the HTML code is applied. In principle, this could still be reverse-engineered because after all the browser needs to be able know what the right answer is. But it is not obvious anymore. For an example, see:

https://www.R-exams.org/templates/sumdiff/

We hope to release that version of the package to CRAN soon but for now you can use

install.packages("exams2forms", repos = "https://R-Forge.R-project.org")

Note that for some details to work correctly, version 2.4-2 of the "exams" package is needed which was released to CRAN earlier today.

Is there a way to hide the correct answer being shown when using 'Inspect' with web developer tools (from any browswer) in exams2webforms? Thanks in advance

Right now, schoice is the the only type of question that does not explicitly include some kind of hmtl tag on the input element that can tell a tech-savvy student the 'answer.' However, if I only use schoice multiple choice questions, many students just spam the radio options until they get the right answer--so in all of the question types, there is a way for bad acting students to elicit correct answers without doing any thinking.
