Hi,

You don't need to worry about your results. If you are into medico, go for it. Taking a 4th drop is not a bad decision at all. But you need to deeply analyze your strategies and have strong motivation for the plan. Cover your weak topics first and then add it to your schedule of daily revisions. You really need to put your best for this level, and you can!

If you are having even a little doubt, I suggest you to start some side degree like in psychology or computers.

For addictions, you can use " digital well being " settings in your smartphone, to limit the usage of certain applications like you are concerned to YouTube. You can limit your applications usage through this setting option.

I hope it clarifies your doubt.

Thank you!
