I wouldn't say I dislike deep thinking and analysis, but Lit seems really intimidating right now, haha. I'm guessing that a lot of time needs to be invested into Lit, in comparison to Lang? Also, do all of the English's make you do 5 SACs each throughout the year?
The amount of time required in each subject is dependent on your strengths and confidence; if you grasp concepts quickly and only need to be told things once, then you probably won't have to spend hours pouring over notes or churning out essays. Whereas, if you consider yourself as having poor memory or repeatedly making the same mistakes, then it might be necessary to invest mroe time in your study.
On the whole, a lot of the 'work' we got for Year 11 and 12 Lit was to 'think about >something.<' Towards the end of class our teacher would conclude a point like '...and so this characters' motivations are a little murkier than we may have thought at first glance. Have a think about that for homework' ...and of course the class titters 'yep, sure, we'll spend all night contemplating these deep questions sir'

Really though, most of the high scoring Lit kids I know were ones who genuinely did think about and engage with their texts- perhaps not to the point of contemplating it at every available opportunity, but certainly had discussions outside of class or researched interesting questions.
One of my teachers said most subjects are as hard as you make them. If you treat Lit like a difficult chore that you have no interest in or proclivity for, then you're gonna have a bad time. But if you see it as an opportunity to say some unique and interesting stuff about a text you find provocative then Lit as a subject will let you do that too.
Lit has 5 SACs; English technically has 6 though one of these is an oral presentation that isn't worth much; not sure about Englang and cbf trawling through the Study Design so maybe someone else can jump in, but I'm pretty sure it'd be 5 as well.
The thing is, in English class I find it quite difficult to put forward something in discussions and such, not because I'm reluctant to raise my hand, it's more like I can't really think of anything constructive to say. I think I'm just generally weak at analysis overall - thinking about hidden themes and motifs etc. Some of the time I literally just sparknotes everything. Would you say this is because I don't have enough exposure to books, news, media? I think I just need to go that one step further to really REALLY analyse but I'm not sure what I should do. 
By all means use sparknotes as a starting point, but that shouldn't be where your analysis finishes. You know why sparknotes is so well known even though it's predominately geared towards the American education system? It's because their analyses are broad enough to apply to whatever essay you're writing - you can just insert their discussion and most English teachers will give you credit for it.
Original discussion doesn't have to be completely innovative - no assessor is expecting an essay that blows their mind and shakes their world view to its core. You just have to talk about the prompt or the text in an interesting way. So when it comes to forming your interpretation of the characters, see if you can ask a whole bunch of questions before you set out to answer them. Using
Romeo & Juliet as an example because everyone knows that play

- Are the lovers to blame for the tragedy?
- What attracts Romeo to Juliet and vice versa? --> do they want each other for the same reasons?
- Are they truly in love?
- What is the significance of the family feud?
- Does the Montague/Capulet reconciliation at the play's end seem legitimate, or will the fighting continue?
- Do we side with one family more than another?
- What makes certain characters (un)sympathetic?
- Are any of the characters truly innocent?
This might seem kind of directionless at first, but it's a starting point. If you need more structure, you could do this scene-by-scene or chapter-by-chapter as a means of extending your thoughts beyond simple summary or basic, general analysis.
A little exercise you might find helpful...
This is also something I've posted before in the QandA thread but I'm lazy so whatevs~~
We're going to look at a textual excerpt; you don't have to know anything about it, in fact it's better if you don't. (I'm adapting this from an Andrew Bovell play called 'Speaking in Tongues' if anyone's interested.)
VALERIE: [answering machine] John, it's me... Valerie. I wish you'd let me do the message.
You sound so... I don't know... distant.To learn how to think properly for English subjects (mainly Lit, which is what I usually use this example for, but tomaito tomahto) all you have to do is answer this question:
What do you know about Valerie and John?That's all. But fair warning, the answer that I have written up at home is over 2000 words long, and that's all without reference to the excerpt came from

Read this once you've thought about it
Most people will fumble for a starting point at first, like 'well, we know she's talking to John on an answering machine, and that she wants to do the message instead of him.' Later, once you get past the basic, denotative stuff, you'll end up in 'assumptions' territory, eg. maybe they're not getting along, and that's why he sounds distant and she's not allowed to do the message. Keep building on this, and eventually you'll reach full blown implications: John is trying to maintain some semblance of power in their marriage by exerting control over petty things like which of them get to record an answering machine message. Meanwhile, Valerie is able to undermine his authority through criticism; she is still able to voice her objections, meaning he does not have complete command over her.
That's not to say there is a 'right' answer. You could go in a completely different direction, eg. The fact that the two are communicating via an answering machine - an innately indirect form of conversation - suggests they are not able to engage with one another on any level. Both John and Valerie are "distant," and without artificial conduits like answering machines between them, their relationship has very little holding it together.
Evidently what I'm talking about here is more like overthinking than just thinking, but perhaps that's appropriate.
Let me be clear: this will not directly help you. You should not spend 200 words in an English body paragraph analysing two sentences from the text/article. This is not about a subject-specific skillset, this is about rewiring your brain to look at things differently.
In the above exercise, I extrapolated from two lines of dialogue and concluded that the couple had a serious communication barrier between them, and were likely in the midst of some confusion regarding the power balance between them. I could be wrong, but that's not the point. The point is that I can justify my thinking.
I had a teacher who conducted a similar exercise in class and ended it with 'of course you couldn't say something ridiculous like 'this excerpt suggests John wants to grow a beard' or anything.' But I disagree.
John's lack of control over Valerie signifies his emasculation ,which is exacerbated by Valerie's implied criticism. She is able to express her wants in no uncertain terms, and her power is marked by a stereotypically feminine "I wish you'd let me" brand of passive aggression. Thus, it seems logical then for John to gravitate towards physicality as a means of reasserting himself with something equally gender-codified; perhaps a handlebar mustache, or even a proper, fully-fledged man-beard - an ideogram of his patient but firm dominance.
Note: I would never seriously write that in an essay. This was an exercise in thinking, and taking my analysis further than the surface level. Do this often enough, and you begin to get a feel for what actually belongs in an essay, and what's just conjecture.
Again, this is all Lit-geared, so hopefully someone else will be better able to address and Englang questions if needed
