I can grasp concepts within my undergrad engineering mathematics courses
But fail to get an exceptional score on the basis of blunders…
eg.
> see 3 and 4 together and auto covert it to 12 in the next line of working out
> see 3 and 2 together in brackets and convert it to 9 in the subsequent workings out irrespective of function

How can I fix this? Its the most persistent problem I face at uni
