First off WELCOME to the forumI've been studying to take the test for the first time and was hoping to take it before the 27th of March. Does this mean I should wait and do it in April?
Yes is you can wait until the release (as of right now 4/6/21) you definitely should as this will give you the most from your Part 107 when you pass. If you took and passed right now, you'd have to take a the Recurrency Training/Testing again once it's released to get the full benefits of the new regulations (night flights etc).
Good luck on your test.
