Im currently self studying for level II qualification. I’ve passed B1 and ready to take B2, ive not yet started studying for the computerised B3/A3 exam as I haven’t decided which is the best to take. I understand I can move over to the A3 if I choose to. Just wondered if anybody had any advise if the A3 exam is more relevant and up to date than the B3? I need to purchase text books and obviously A3 test book is more expensive!
