i currently have a 50% in maths class i still have to hand in 2 assignemnts , do one more test, my culminating and my exams. My culminating is worth 15%, my exam 15%, my test 8.75%. and my 2 assignement are replacement tests. i did bad on my test so my teacher gave me those 2 assignement on my first test i got 44% and on my 2nd test 43%. whatever i will have on my assignement he will average them with my test and that will be my test mark. so imagine if i have an 80% on all of those things what would be my final grade?

To calculate your final grade, you need to take into account the weighting of each assignment. Based on the information provided, your final grade can be calculated as follows:

1. Assignments:
- First assignment: 44% (replacement test)
- Second assignment: 43% (replacement test)

Average of assignments: (44% + 43%) / 2 = 43.5%

2. Test:
- Average of assignments: 43.5%
- Weight of test: 8.75%

Weighted test mark: (43.5% * 8.75%) / 100 = 3.81125%

3. Culminating:
- Mark: 80%
- Weight: 15%

Weighted culminating mark: (80% * 15%) / 100 = 12%

4. Exam:
- Mark: 80%
- Weight: 15%

Weighted exam mark: (80% * 15%) / 100 = 12%

Finally, add up all the weighted components to determine your final grade:

Final grade = Average of Assignments + Weighted test mark + Weighted culminating mark + Weighted exam mark
= 43.5% + 3.81125% + 12% + 12%
= 71.31125%

Therefore, if you have 80% on all components, your estimated final grade would be approximately 71.31%.
