These online classes were slow-moving
These online classes were slow-moving, repetitive, and tedious with the odd nugget of useful information like tiny little oases in a vast parched desert. We cancelled our contract with the correct amount of notice and the firm decided to keep an extra month of fees anyway (you register by paying the first month and *then* you pay a month ahead). I've heard someone else had the same issue of not getting a refund after cancelling in time.
So be aware that even if you do sign up to see if it is for you and decide to cancel, you will probably never see the month in advance you paid back. There are far more engaging online learning classes. Atom Learning is good, and I'm sure there are others. But for the price of these classes (170 a week), plus the 245 blah blah joining fee, you can get a lot of 1:1 tuition with someone who will teach at the correct pace.
