UCB undergraduate admission update form

Hello, I am a transfer student who was admitted to UCB. I wanted to drop my physics course in this spring quarter because it was only required for UCLA and I got rejected from them. I emailed my ucb admission officer and he confirmed that I can drop the course without jeopardizing my admission. However, I will have a record that I dropped Physics course with W on it. Will it be still ok to drop the course? He is not replying my email on this question and I have to submit the form by tomorrow. I also contacted ucb admission office and the person said some student drop with W and some are not and it seems like my admission officer already confirmed that it’s ok to drop the course. What should I do?
