All browsers are slightly different but, most work in broadly the same way. The following instructions should work in most current browsers.
Go to the page that you want to select as your homepage.
Open the main internet tools menu in your browser - this may be called Tools or Edit (depending on your browser and operating system).
Select the tab marked General, Preferences,
Options or Internet Options (depending on your browser).
You may see a button marked 'Use current page' or 'Use current'. If so, click this button then click OK. The page you were visiting should be saved as your homepage and you won't need to do anything else.
If not, look for a box entitled 'Homepage', 'Homepage location' or similar, which will contain the web address (web address) of your current homepage.
Type http://www.bbc.co.uk/scotland, or the address of the page that you want, into this box and click OK. Your new homepage will be set.
