Total credits for your second year: 20 + 20 + 20 + 10 + 10 + 10 + 30 = 120

Final grade for second year = weight1*grade1 + weight2*grade 2+....
= 50*(20/120) + 40*(20/120) + 50*(20/120) + 48*(10/120) + 35*(10/120) + 40*(10/120) + 60*(30/120)
= 48.58%
You scored a third class for your second year.

This is the answer I found in many places- To calculate your weighted average, you need to multiply each grade by the number of credits it carries, then sum up these values and divide by the total number of credits. Let's calculate your weighted average based on the information you provided: Organic: 50/100 * 20 credits = 1000 Physical: 40/100 * 20 credits = 800 Inorganic: 50/100 * 20 credits = 1000 Sustainable: 48/100 * 10 credits = 480 Analytical: 35/100 * 10 credits = 350 Medicinal: 40/100 * 10 credits = 400 Lab: 60/100 * 30 credits = 1800 Total weighted points: 1000 + 800 + 1000 + 480 + 350 + 400 + 1800 = 5830 Total credits: 20 + 20 + 20 + 10 + 10 + 10 + 30 = 100 Weighted average: 5830 / 100 = 58.3 Therefore, your weighted average is 58.3. Which method is correct and why?
