What are different ways to check your solutions for simple Resistive Circuits?

Or even in general cases, how I can make sure that my answer is right?

I am making very stupid mistakes (mostly algebra problems and using wrong directions),

so I want to make sure that I don't repeat these mistakes in the exam.

I am not very familiar with circuits, so I cannot use reality check (in Physics, it's very simple to guess the answer even without doing detailed calculations)

2. Relevant equations

I am using Nodal Analysis and Mesh Analysis to solve them

3. The attempt at a solution

Here's a checklist I developed:

# Reviewing Nodal Analysis Questions:

1. I should write detailed steps (neatly) leaving space between lines

2. I should simplify my equations before solving them on calculator

3. After Calculations:

1. See if I have used right numbers

2. See if my equations are right

3. See if my solutions meet with my equations

* See if I have right directions of currents as indicated by diagram

4. If time available, use other techniques to confirm my answers

5. See if power analysis agree...

Thanks.
