On our website (www.ift.world) we make the below claim:
"We are confident that the summary videos will cover more than 80% of what you are likely to see on your essay exam."
For 2019 this is purely our prediction – however for 2018, IFT summary videos did cover well over 80% of what was on the actual 2018 essay exam!
