Would also like to know the answer to this..
Platinum Chess Mentor lessons

However reviewing previous lessons from previous days seem to count for your daily lessons (it does for me)
That is why I think the other membership options besides diamond are not very useful. It would be fair if platinum had at least 25-30 lessons per day considering you still pay for it. I would not be happy with only 5 lessons per day, that probably takes what, a couple of minutes?
Platinum membership on Chess.com offers 5 lessons a day. Do these include reviewing previously completed lessons or does it mean 5 new lessons? What happens if 5 lessons have been exceeded (I believe I have done so once by accident)?
