I was doing a test. With a few questions to go I had only one heart left so I thought I would get one from the lingot store. That was ok. But then I couldn't get back to the test. So I lost all the work I had done to that point and also lost the heart that I had just picked up! Help!
Remember to buy the heart refill BEFORE going into tests. To get to the lingot store you have to exit the lessons and tests, therefore losing all your progress
Thanks for the advice. Unfortunately I don't know if I'm going to need an extra heart before starting the test!
It always helps to buy it, along with a streak freeze if you want one, then you can use it when you need it, it should come up at the top of the question area (next to the hearts) when you lose one
