You get one remap per year, plus 2 bonus remaps you can spend at any time. Plan your remaps accordingly.
A skill planner like EveMon is really helpful.
For me, 1st remap was Per/WP for ships, gunnery and missiles
2nd remap Int/Mem for armor and shields
3rd remap for Drones (right up to T2 heavy and sentry drones)
This was part of a 2 year strategy.
Edit. protip: train Cybernetics to lvl 4 and get some ‘standard’ implants for the attributes you are training (only 2 at a time). Then train Informorph Psychology and add a Jump Clone or two. These will let you “jump” out of your implants to go do things like PvP or whatever and not feel you are risking your implants. As you progress you will see that Standard attribute implants are not that expensive anyway.
Don’t feel like you are “losing” anything by not having implants in your head, CCP gives you enough free skillpoints to more than make up for this. Don’t miss out on the fun of the game for simply training!
