I have a question (code given below) which has subparts. Part (a) is further divided into 3 parts: i, ii and iii, whereas Part (b) does not contain any subparts. The total points awarded to this question is 15 of which Part (a) carries 11 marks and Part (b) 4 marks.
There exists the macro \totalpoints in the exam class package that gives me the 11 + 4 = 15 points for the whole question. However there is no macro to compute the number of points (marks) for Part (a) only. I would like a macro that also sums the marks for Part (a) i.e. 2 + 6 + 3 for the subparts to give 11. As the code is today, I have to manually write \part[11] i.e. I myself must manually do the addition of 2 + 6 + 3. I would like a macro that I can just use as \part[\mymacro] that will be equivalent to \part[11].
\totalpoints should also recognise the macro so that I still get 11 + 4 = 15 as the total points for the question. The macro should perhaps just be visible to one subquestion of a whole question so that it can be used in other subquestions of other questions to count the respective sums overthere.

My second question is here and it is worth 4 points. There are no subparts.

Based on the answer proposed by @John Kormylo in order for the macro to cater for half points as well, the correct output is not obtained. See output below:
We do get 9 1/2 marks as the required sum for the subpart total subtotal. However there are three extras 1/2 inserted between Part (ii) and Part (iii). Moreover now \totalpoints is ignoring the 1/2 marks. The aux file is shown below:

\subtotalcommand twice within the same question, it increases thetotalpointsvalue. Im not sure why it does this?
