Projectiles - S There's no weapon Sokka is more skilled with than his boomerang, since he has used it as a weapon since he was just a child. By mentally estimating the trajectory of an enemy's attack, he can aim his weapon to hit opponents he can't even see. His talents carry over to using other projectiles like knives, tomahawks, and similar weapons. It doesn't carry over to bows, crossbows, or guns though.
Sword Fighting - A A combination of his own experiences, training with Master Piandao and his ongoing studies, Sokka has developed into a master swordsman using the Jian sword. By the time of Black Sun, he had enough skill shear a man's spear, while mid-leap. At the time of his initial training, he had very little in the way of skill, just natural talent and quick reflexes. As a prodigy, he's proved to be a quick learner and quickly incorporated Piandao's teachings, in spite of the short time spent training. He's continuing to study with Okita Souji in Tennen Rishin Style, becoming disciplined in Kenjutsu and Kendo. This training is ongoing since May (2010/Year 3).
Martial Arts - B Thanks to his brief training by Suki and his own experience dealing with martial arts fighters like Ty Lee, Sokka can usually avoid getting hit and knows enough to turn an unskilled fighter's strength against them. Training in Luceti has made him a better combatant, thanks to his training in Jujutsu with Okita Souji and Akido with Derek Bliss. This training is ongoing since May (2010/Year 3).
Explosives - B Following Hakoda's example, Sokka has used the advantage of having resources and time in Luceti to keep himself stocked on bombs. Through his father's own lessons, some input from the Mechanist, and his own research and experimentation, he's created an arsenal of bombs to use. He prefers to use smoke bombs, but he has other explosives he uses in times of drafts. Although capable of making them himself, he often requests explosive boomerangs from the Malnosso for drafts.
Acrobatics/Agility - B Compared to his friends, Sokka is a little more limited in this regard. But his duel with Piandao showed him capable of pulling off more than he would seem capable of in the rush of battle. He has a great sense of balance, can effortlessly pull off cartwheels in combat, and effortlessly jump from one platform to another. During Black Sun, he demonstrated the ability to jump on top of a Komodo Rhino's head, even while weighed down by armor and weapons. His time in Luceti has improved these skills, but he's still quite a bit behind his friends in athletic prowess.
Alchemy - C With the guidance of Edward Elric and lots and lots of research, Sokka is starting to form an understanding of alchemy. He's able to form basic alchemy circles, but it usually requires time and effort to make a successful one, so he's far from being able to do one quickly on the fly. He's figured out how to transmute mute and he's working on techniques to transmute the components necessary to construct the variety of explosives he likes to keep on him in order to reduce the time necessary to construct them.
Other - B Sokka's skills with other weapons vary, but he's adept at picking up just about any weapon and being able to use it fairly effectively. This is demonstrated by how quickly he was able to pick up nunchucks and show an extreme proficiency in their use, despite having never used them before.
Filial Magic
Kipinn (Air) - S Due to how weak it is, Sokka found Kipinn wasn't much use in attacks beyond causing distractions (either by blowing air or throwing his voice), but he has developed a technique of increasing the strength and range of his boomerang. He's working on a way of keeping a gust of wind inside the boomerang's arc that would allow it to carry small objects back to him.
Eferin (Fire) - S Sokka's affinity from fire was developed from his time in the smithy. He wasn't able to get Eferin's attention until he accidentally drank rum in the forest and started a huge fire as a result. Since then, he's developing the magic as a way to fight firebending, by learning to control an enemy's fire and stop it. He's developed a rather useless trick that involves making his sword appear to be on fire.
Tsinku (Lightning) - A Sokka was only able to catch Tsinku's interest when he started spouting haikus off to him about his frustration at being ignored. Lightning is tricky to work with and Sokka's attempts to use anything but small sparks from a battery have not ended well. He nearly blew himself up when he channeled his own electricity into a training dummy. Another time, he blew the fuse in a house when he channeled the electricty from an open circuit through his sword.
Hyt (Light) - A Sokka tried to contact Hyt for a brief time with Xion and din't make any headway. After several months of infrequent attempts, he's finally gained enough mastery to create orbs of light and brief flashes.
Nala (Healing) - F At first, Sokka could hear Nala plainly. But he ignored herin favor of better spirits. Lately he's been trying to contact her, but her voice is faint. His own frustration at other things has made it hard for him to pay attention, due to a large part that he doesn't really want to be stuck on the sidelines healing people. As a result, he hasn't been able to learn anything significant yet.
Faeren (Earth) - N/A Sokka has heard her voice, but has yet to make contact.
Sona (Water) - N/A Sokka often hears her voice on his canoe trips down the river, but hasn't made contact. Waterbending is Katara's thing, not his.
Art
Poetry - A Sokka has a gift for wordplay, effortlessly being able to come up with haikus off the top of his head, even adding rhyme and rhythm to them in the process.
Music - C Sokka's music is unrefined, but has potential if ever developed. He has at least some experience with a flute, though he barely knows how to play one. He has a surpisingly good singing voice that is only ever heard in the shower.
Artwork - C Sokka's art is horrible and barely recognizable for the subject he's depicting. His painting isn't much better. This has yet to dissuade him. Practice with alchemy has at least taught him how to make good use of circles and straight lines.
Sculpting - D As bad as his art, if not worse. His attempts at carving wood or building something from sand both had horrendous results. He doesn't understand the criticism.
Crafting
Smithing - A Sokka learned more than just fighting under Piandao's tutelage. As one of the Fire Nation's swordmakers, many of his skills were passed down to Sokka. That same knowledge he later used to forge Appa's armor for the Day of Black Sun. In Luceti, he has refined this knowledge and expanded what he knows to being able to work with various weapons and armor now. His technique has continue to improve and with the help of Leon, he's able to forge 'enchanted weapons' imbued with elemental powers.
Shipbuilding - B Growing up in the South Pole, Sokka helped work on various boats with his father before he was sent off to war. In the two years that passed, Sokka was the one in charge of keeping their boats in working condition. In Luceti, there is no dried animal skins or whale bone to make boats with, so Sokka has had to learn to work with wood. His results have been effective, although his canoes are not exceptional by any means.
Engineering - B Sokka has some talent for engineering. He is significantly skilled at this in his own world, which is on the verge of technological revolutions. However what he knows and is capable of doesn't quite compare to what has been accomplished in other worlds. In Luceti, he has been working with what is available to him in attempts to better understand more futuristic technology. With the aid of lots of "How To" books, he's knowledgable enough to make repairs on the usual sorts of electronic devices that are made readily available in Luceti.
Tailoring - D Stitching clothes back together? That's Katara's job. Of course, Sokka could do it if he had to. It just wouldn't look very good. Or hold up for long.
Survival
Navigation - A Sokka is a 'master' map reader and navigator, usually being the one his friends rely on to get them where they're going. For him it's part intelligence and part intuition. During their travels, he even had each of their days scheduled out based on how long it would take to travel from their starting point to the rendezvous spot with his father's fleet. One of his true loves is expensive atlases.
Fishing - B Sokka is a skilled fishermen, his talents being considered 'off the hook' in his own opinion. He is skilled both at angling and at spearfishing, depending on the size and type of fish. He's even gone fishing using nets and a few times accompanied his father on whaling expeditions when he was younger.
Hunting - B Being from a hunter-gatherer society and his tribe's primary hunter for two years, Sokka is a skilled hunter. His bad luck and clumsiness often proves to be his downfall though. However when the opportunity does arise, Sokka doesn't hesitate to kill his prey and eat what he's found. He isn't choosy about what he hunts and in Luceti he often goes for smaller game.
Woodcraft - B Sokka is quite skilled at surviving out in the wilderness, especially given that he spent the last year camping out all across the Earth Kingdom and Fire Nation, only having permanent shelter for brief periods of time. He has no difficulty building fires and temporary shelters, tracking down animals, foraging, and other survival techniques. Many of these are significantly used for adapting to extremely cold climates, such as the South Pole.
Cooking - C Sokka isn't an exceptional cook, having never needed to do given that it was the role of women to do so. He is however skilled enough to cook meat and make sure it's fully cooked without being burnt. Every now and then he gets the urge to experiment and tends to have mixed results.
Academic
Science/Technology -A In regards to his own world, Sokka's grasp of technology and science is impressive, especially given his background. His inventiveness and keen insight are something he inherited from his father and honed by his meeting the Mechanist and understanding Fire Nation technology. Two years in Luceti has significantly increased his understanding of science and he's talented enough to tinker with and repair modern electronic devices. His ongoing studies in alchemy has broadened his scientific research into fields he previously had no interest in as well.
Strategy - B Sokka has developed into something of a strategist, being the one who formulated the plan for the invasion on the Day of Black Sun, to the point of timing the entire attack so they would be in Fire Nation capitol during the short 8-minute window that the eclipse would block firebending. His plan's only failure was that Azula learned of the eclipse from the Earth King beforehand. Because he looks at the big picture, he knows when to pick his fights and when it's better to conserve time and resources for the more important battles.
Mathematics - A Although Sokka hasn't spent much time learning complicated mathematics, he is able to figure out numbers quickly in his head. This is particularly evidenced by the schedule leading to the Day of Black Sun. After being delayed, he was able to quickly calculate that if they woke up 43 minutes earlier each day, they could remain on his schedule. Thanks to his time in Luceti in both schooling and personal pursuits, he's significantly improved his understanding of mathematics and is capable of working out complex calculations in his head or on paper.
Writing - C His handwriting is fairly poor. And easily recognizable.
History - C Sokka never learned much history from his own world, beyond what was told to him. He has little interest in learning the history of other worlds either.
