Strathclyde Engineering Fundamentals
If anyones dc is interested in engineering Ds did this a couple of years ago when in S5. It is a funded online course and running again November to February, approx 100hrs commitment but do at your own pace and mostly short videos and multiple choice quiz type assessments.
I have been keeping an eye out for it restarting for a friend, but not ideal timing as they will be revising for prelims and highers, but someone might be interested (ds did his end may - june, but they didnt run last year at that time, perhaps no funding).
Ds found it helped confirm he wanted to do engineering and prompted further interest before it got to application and PS writing time and helped with some ideas of what to write about.
