Please write down the question in full so that we may make out the problem
I am using the Cambridge IGCSE and O Level Additional Mathematics Coursebook (Third Edition). You can find the full question from that book.
HI MR LIM
hi
Hi, could you explain what it means by follow through FT in the marking scheme? : 11:40
FT follow through after error. Answer before is wrong, but the steps here is correct, then can give the M marks with FT.
Types of mark M Method marks, awarded for a valid method applied to the problem. A Accuracy mark, awarded for a correct answer or intermediate step correctly obtained. For accuracy marks to be given, the associated Method mark must be earned or implied. B Mark for a correct result or statement independent of Method marks. When a part of a question has two or more ‘method’ steps, the M marks are in principle independent unless the scheme specifically says otherwise; and similarly where there are several B marks allocated. The notation ‘dep’ is used to indicate that a particular M or B mark is dependent on an earlier mark in the scheme. Abbreviations awrt answers which round to cao correct answer only dep dependent FT follow through after error isw ignore subsequent working nfww not from wrong working oe or equivalent rot rounded or truncated SC Special Case soi seen or implied
