Very smooth purchase. I suggest you to develop your own app, so that we can purchase directly from the store. Because not every one uses credit card( i have to apply for new CC).
The best thing I like about it, is the price, they are competitive very cheap.
Keep going ,
All the best
Overall good, I am able to do some focused preparation
I am finding few numerical questions / answers are not correct. I do not remember the tests.
Also I am not finding questions related to profit / loss , rate of work and something similar.
Could you please point me if there are few papers covering that.
