This is a simple CLI tool that I created for my colleagues from Salesforce-trainers group. It simply caclculates weighted average from partial Exam scores 3 salesforce developer exams. But feel free to use this tools --edit flag to edit exams.json (add/remove/modify exams). It is not prefect and I mostly just used this Package to try out some NodeJS features.
Currently this package is only supported Windows, Mac and Linux.
npm install -g forcecalc
This launches the main. You will be prompted with everything you need to Calculate your Final Exam Score.
This feature opens json file with all exam data. You can modify and add new Exams. All exams do have topics and there you can find a topics name and weight. NOTE: You can not mofify calculation formula only data passed there.
