Online Competitions

Hi everyone, I am just wondering but are there any oninle competitions for STEM students, for example, ExploraVision is one since you just submit your paper online
Please list any other online competitions you know of.

Thanks!!

I have a similar query

There are many math competitions that are running online. My D is competing at HMMT, PUMaC, CMIMC, and is looking at JHMT.

Most have been in-person and team based in the past, but are on-line and at least some allow individual entry this year.

Several are coming up soon, so may be past registration deadlines, though I know JHMT is still open.
