Hi there,
I agree with the other coaches - your questions are a bit too generic.
Problems in the math part for example could be:
- Wrong math
- Very slow math
- Lack of structure presenting the math
- Lack of connection of the math results with the goal
- Took wrong numbers/made wrong assumptions
The same thing is true for structuring. Without knowing the specific issue, it is not possible to provide good suggestions.
If you know already which areas you could improve, I would recommend you edit the question or ask a new one with the specific parts you find challenging so that we can help you more.
If instead you are unsure about which are the improvement points, I agree with Ian that a coach could be a good investment.
Hope this helps,
Francesco
