No problem. Yes, you'll continue to receive all of your money. The only time it will stop is if you're found fit for work once a decision is made. Of you're in the Support Group at the moment and the decision is to place you in the WRAG then you'll receive slightly less money. You need to make sure the form is returned no later than the date stated in the letter. If you're late returning it then your money could stop for failing to return the form. Expect another face to face assessment as most people have them. Make sure you send evidence with the form because they very rarely contact anyone for any evidence. Good luck.
