Slow Down Website Speed

Hello As master study have more than 20 plugin and 35 plus pages its really slow down my website page speed.

I have buy premium business web hosting because I do not want to face issues about web page speed.

And If I talk About Current Conditions If any one type my domain name and click enter it takes around 25 to 35 seconds to load first page of website.

How can i make my web page speed super faster within masterstudy lms theme.
