Hi,
I have passed the test recently & believe me [and Waheed ofcourse 🙂 ] that this is a piece of cake.
Do not panic & remain calm.
While studying, make a note of the statistics like % of minorities, population in UK, dates, how many days are bank holidays, etc.
Try memorising them. The other bits are easy.
If you are able to get correct scores on the practise tests on this site then you will pass.
Again, relax....think of the worst case scenario...you will just lose some money if you fail. Thats all. Noone will stop you from appearing again....which will not be needed anyways :)
Best wishes. Come back again on Wednesday to say you passed :D
