Are you looking to move to a different pathway for the July session? Do you have concerns about the overlap?
The overlap can be broken into 3 parts:
1st part: New July students are getting used to the various collaboration channels. Hopefully, you have to spend minimal effort here.
2nd part: You are learning about the new pathway and doing your first self-assessment. At this point you are handling 2 projects. You have to put in double the effort for ~1 week. I would not recommend a mix of ML and Bioinformatics if you are new to either, unless you are willing to put in your 200%.
3rd part: The June teams are primarily engaged in showcasing/ celebrating! This part should be possible to handle along with new pathway with a little extra effort.
