Studying 6 Weeks for CAIA L1 (with general industry experience) - Impossible?

Hi - I currently work in the alternative investments industry and for the last 24hrs have been debating if its too late to commit to the March CAIA L1. This would only give me 6-7 weeks of study/prep time while maintaining full time work. I could map out these weeks to have roughly 100-150hrs of study time (possibly more if I really commit all my free time to it).
With already having general industry knowledge is this too short of a time window to study/prep and pass CAIA L1? Curious if anyone has had similar experiences or can attest to the difficulty of the exam with having experience/knowledge. Thanks!
