Different ways to check the answers

Homework Statement

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)

Homework Equations

I am using Nodal Analysis and Mesh Analysis to solve them

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.
