Grade Calculator Update to CGPA Planner

[vanshbothra]

• Create a new branch called 'grade-calculator' from sg-main ka 'main' branch.
• Git pull on your local and switch to that branch.
• Go to src/views/platform/cgpa-planner2.ejs
• There will be 2 divs each with ID 'evaluations' and 'raiseGPASection', do NOT change those at all. Create a new div with the same indent as those 2 divs described earlier with the ID 'updateGrades' and add your portion of frontend there. Basically the new div should be inside '
  '.
• Try using inline css or define those within the styles of this ejs file only, so not use a separate css file for now and try to match the current UI of the webpage.
• Write the js functions inside the Githubissues.
• Githubissues is a development platform for aggregating issues.
