Work out the score I need on my final

Works out the score you need on your final to reach a target grade, using the weights and marks you give, with the calculation shown.

Task: Work out which score I need on my final to reach my target grade, and show the calculation. Context: My target is [target grade or percentage] in [course name]. The grading scheme from my syllabus is [weights of each component, for example 30% homework]. My marks so far are [your marks per component]. Rounding rules in my syllabus are [rounding rule, or "not stated"]. Rules: - Use only the weights and marks I gave. If they do not add up to 100%, or something is missing, say what and ask me before you calculate. - Show the formula in words, then every step of the calculation with the numbers. - Calculate the needed score for my target and for one grade lower, and say whether each is possible within the final's maximum. - Tell me to confirm the result against my syllabus or my teacher, since grading rules differ between schools. Result: The formula, the steps and then a table with two rows (target and one grade lower) and the columns needed score and possible. One sentence on the result.
