This Google sheet is linked to a database of drugs (some exam-relevant, some completely random and useless for revision purposes). Agree: the <iframe> is a poor design choice. Those wishing to access the Google Sheet directly may do so instead using this link. In this thing, you can pick up to three drugs and compare them in a table side by side, which is what CICM often want you to do. It is impossible to say whether this will improve your learning experience.
