You should all know this is inline scripting and is not a good practice at all...with that said you should definitively use Js o Jquery for this type of things:

HTML

 <!DOCTYPE html> 
 <html> 
 <head> 
 <meta charset="ISO-8859-1"> 
 <title>Online Student Portal</title> 
 </head> 
 <body> 
 <form action="">
 <input type="button" id="myButton" value="Add"/>
 </form> 
 </body> 
 </html>

JQuery

 var button_my_button = "#myButton";
 $(button_my_button).click(function(){
 window.location.href='Students.html';
 });

Javascript

 //get a reference to the element
 var myBtn = document.getElementById('myButton');

 //add event listener
 myBtn.addEventListener('click', function(event) {
 window.location.href='Students.html';
 });
