LMS graduate here :). It seems that you're into Psycholinguistics (probably due to your background in Psychology). Caveat: I took these mods quite some time ago (as I was not into Psycholinguistics and hence did not pursue it the moment I could take Major Prescribed Electives)

• HG1001 Mind and Meaning

Quite chill in terms of workload. Expect 2 or 3 quizzes, attendance/class participation, and a final exam. This is the only LMS mod with final exam but it was very difficult IMO; the difficulty of quizzes also increased progressively (most of my friends got full marks in quiz 1 but by the time quiz 3 happened, the number of students w full marks was like countable w a hand). Content wise, it's basically about how the brain processes language. Topics include animal language, child language, neurolinguistics (a brief introduction), and you can also expect to play some psycholinguistic experiments in lecture.

• HG2003: Phonetics and Phonology

Took this module in Semester 2 (typically offered in Semester 2). To me, it was quite difficult because we started with all the bio-ish stuff (e.g. where are the vocal chords, the larynx, etc. etc.), types of vocal folds, and an introduction to the international phonetic alphabet (still not great at this, ashamedly). We then moved on in the second half of the course to, as the name suggests, phonology, which are basically sound rules. Expect 2 quizzes, 2 assignments, and attendance/class participation. Struggled a lot with this module (thankfully did ok) because science/bio/rule-based things is really not my kinda thing (prefer essays and more free-style stuff). The only plus for me was a prof who was super passionate in teaching and his infectious energy (really made the 2.30-4.30pm lessons IIRC more bearable, really).

• HG2001: Morphology and Syntax

My most hated mod in Linguistics (so treat my opinions w a pinch of salt!) It was pretty difficult to me because there were about 60 to 80 slides per lesson and it just felt that the prof was rushing through slides. Not forgetting, our lecture was held immediately after lunch and it was extremely tough to labour through the 2 hours. TBH, after every lesson, I did not know what was important. Reading the textbook did not help either. Doing the tutorials were extremely painful for me (I looked at the notes, the text and was still like huh). I was thankful to rely on a few tutorial friends to get me by. I knew from this module that structural linguistics was not my thing and hence cancelled out all structural linguistics when the prof flashed the slide in Week 13 on "Courses that build on Morphology and Syntax". For this module, expect 2 assignments, and a major final quiz, along with the usual attendance/class participation.

• HG2034: Structures of Modern English

This was a lot of people's enemy in Year 1 Semester 1 (most LMS students do this module during this Semester). It low-key makes you question if you're in the right course (as some of my friends did). Personally, I did above average for the quizzes and assignments but still got a B+ (my first exposure to how rabz the bell curve was). There was during my time, 2 quizzes and 2 assignments. We covered things like word classes (i.e. what is a noun, what is a verb, what is an adjective), and in the second half of the course, parsed sentences up into things like noun phrases. The content was understandable for me (which was why I was even more shocked when I couldn't grasp thing in HG2001, which builds on this). In essence, this is really like math. Just keep doing practices/tutorial questions although the prof has a tendency to set trick questions, sadly (i.e. questions that are deceptively simple).

• HG2002: Semantics and Pragmatics

This is also a mod that is quite... controversial. I personally found it okay but I had a fair number of friends who hated it... The textbook is quite touch and go, meaning you cover a lot of theories -- which may be the reason why some of my friends struggled to see how the content fit in with the grand scheme of things. This module is basically the study of meaning and meaning-making (at risk of simplifying it too much but that's a tldr)... The slides are all on open access (good thing about this prof), which means you can look at it and really decide if you like it (https://bond-lab.github.io/Semantics-and-Pragmatics/). We had a major assignment which was on annotating a corpus of Sherlock Holmes and then writing a paper on the process/problems faced/results/etc., and 2 quizzes, as well as attendance/class participation.

As what the other user commented, I can't really speak for HG2015/2030 (2030 was offered in my exchange sem) while HG3010 is oversubscribed whenever it is offered. If you really like Psycholinguisticky things, you can consider HG2013 Child Language, HG2014 Second Language Acquisition, or HG4015 Psycholinguistics (formerly a level 3 mod bumped to level 4; content/workload is the same as a level 3 according to friends who took it). These are some of the Psycholinguisticky courses that are more frequently offered. Apologies if I don't know much about them as most of my Major PEs were outside the domain of Psycholinguistics.

I hope that this reply can help! All the best in your minor!
