How many W's is too many?

I’m at a CC right now and I just changed my major. I was planning on geology but the science and math has turned out to be way too difficult and I currently have 2 W’s on my transcript (one is in PE because I got injured). I’m about to drop trigonometry and I changed my major to anthropology so I only need to take stats and humanities from now on. I want to apply to CSU’s like Humboldt, Long Beach, San Diego, and San Francisco. I will most likely be at this CC for a total of 3 years.

I was wondering how many W’s on a transcript is too many? I really want to try and avoid retaking these courses.

If they are early in your time at the CC, there should be no problem.
