fmk is actually a pretty crappy normal in 3s
Ken’s F.MK is TRASH homie. i’m seeing alot of ken beginners online do a dp, super or ex hurricane after a blocked f.mk and thats really a sf4 scrub tactic not a mixup.
uoh edit- pherai beat me to it 
f.mk 
combo wise depending on your ability level work on getting consistent with his target combo. When you can do it without any mistake, try to end it with a jab shoryu or an ex hadou. Other than that there is a tremendous amount that you can learn with almost no technical ability. spend some time checking out the spacing and speed on his normals.
If you’re having trouble cancelling a move into super, remember you can one qcf sort of ahead of time by buffering it. For instance if you’re trying to get the feel for crouching mk cancelled into SA3; try doing the first qcf input as you’re crouching and hitting mk, then input the second qcf right after and hit kick. Kind of hard to explain but basically experiment with how inputs feel. Everyone does them a bit differently and there are ways to make things easier on yourself.
take your time, don’t let people online bother you. play arcade a whole bunch to get some exposure to other character’s moves too and how they hit/what they do. Alternatively go into training with other characters and just see what they can do and what stuff looks like. explore the game, it’s fun.
practice is essentially worthless unless you have an objective and you’re enjoying it. As long as you play with a goal in mind you’ll progress and you’ll recognize your progression (which helps you progress even further).
I’m saying for footsies man, counter poking with it, not just throwing it out there like a tard.
and yeah cMK has a lot of uses as a poke as well and also a shit ton of mixup options if someone blocks or parries it.
also upon rereading my first post I forgot to specify cMK, so I can understand the confusion.
cr.forward, cr.strong, and standing fierce… Or you could play Ken like me and pretend cr.roundhouse is like Dudley’s and be surprised when you can’t combo after it.
I am assuming here that cr and c meaning counter ? And if my assumption is correct … I don’t know what that actually means 
cr or c means crouching.
cl means close (as in you’re next to the opponent).
f means forward, b means back.
Cheers. I knew f, b, d, u My bad.
Jargon explained:
Man you chose a difficult game to start out with but i think 3rd strike will teach you stuff that will carry on to sf4.but if you keep losing dont let that bring you down you got a lot of people on here who are willing to help
I suggest maybe going down to a local game shop and see if you can find Anniversary Edition. It’s SFII: Super Turbo and SF3. I would start by learning core SF fundamentals from Super Turbo. Not only can ST help a lot with your game but it’s classic for a reason. However I don’t suggest SFIV due to some particular bad habits a player can develop. SF3 can be particularly unforgiving due to the knowledge and skill set many players have developed over the years. It’s great game but can be very different from some of the other SF’s you may have played in the past.
Also, as the other lads above mentioned. Take your time, avoid the impulse to Dragon Punch every time you wake up after a knock down or repeat crouching roundhouse. These things will get you K.O.'d in a rather convincing fashion. 3S is about developing strategies (avoid doing the same thing repeatedly) and out smarting your opponent. Watch high level matches and learn from them and also learn to lose, and in particular learn why you lost. It will bring you closer to winning.
P.S. Just because parry exists does not mean you should try and parry everything. Believe you me, I still loose matches trying to be stylish.
Thanks once more to all. Been practising and enjoying it. Playing Arcade and a little online(to mix it up). One thing I have noticed online is that I seem to get pinned in the corners by the more aggressive opponents. I seem to panic cause I don’t really know how to get out. Quite often I try to Dragon Punch out but get hammered back.
Any suggestions as to what to do in these situations ?
This is where nerves come in to play. First off, calm down. If you get nervous, you’ll miss inputs, do things too early / late, & you’ll stop thinking. This will happen, but it will help you later if you learn to block. The standard is staying in cr. block position and watching for overheads. After that, watch for throws if they are in throw range. This takes quite a bit of concentration at first, but sooner or later it will become natural. Watch for highs, lows, and tick-throw setups. Teching throws is the hardest and comes with experience, but none of these defensive techniques are hard to pick-up. They do take a lot of practice to master.
Secondly, evaluate the situation: if you try to jump out, will he be able to react and jump attack to put you back in? Honestly, sometimes the best decision is to stay put in the corner. At least it eliminates certain cross-ups (though some cross-ups will still work).
Lastly, after you level-up your defense, apply some counter-offensive maneuvers.

Have fun & good luck.
Pro tip: Go fuck yourself.
There’s really nothing I can say that hasn’t already been covered OP, but I will emphasize one thing. Don’t give up and have fun. Fighting games aren’t easy, but it’s a labor of love.
